Description

Technical Field

[0001] This utility model belongs to the field of petroleum exploration and extraction technology, and relates to a pumping fluid detection device. Background Technology

[0002] When oil wells are extracted using pumping methods, the pumping fluid becomes a crucial key to understanding reservoir characteristics and the extraction process. It carries vital information about pressure, temperature, composition, and other crucial data from deep within the reservoir. This information not only determines whether the well can efficiently bring oil resources from underground to the surface but also affects the safe and stable operation of the entire extraction process.

[0003] The pumping fluid has a complex composition, containing petroleum, natural gas, water, and small amounts of impurities. The content and properties of petroleum in the pumping fluid directly affect production and economic benefits. Excessive water content increases transportation difficulty and costs, and may even lead to increased fluid column density within the wellbore, creating back pressure on the oil reservoir and hindering further oil flow, severely impacting extraction efficiency. The content and state of natural gas are also crucial. Appropriate amounts of dissolved natural gas can reduce petroleum viscosity to some extent, facilitating flow; however, excessive precipitation and accumulation of natural gas can cause pressure fluctuations within the wellbore and even pose safety hazards such as explosions.

[0004] Furthermore, the physicochemical properties of the pumping fluid, such as viscosity, density, and corrosivity, have a profound impact on the operation and lifespan of extraction equipment. High-viscosity pumping fluids increase the load on pumping equipment, accelerate equipment wear, and increase maintenance costs and frequency. Corrosive components can corrode critical equipment such as downhole tubing and pumping pumps, causing equipment failures, leading to the interruption of extraction operations, and resulting in huge economic losses and safety risks to oil extraction.

[0005] Traditional detection methods mainly rely on manual sampling and laboratory analysis, which have the following problems: (1) Lag: The laboratory analysis cycle is long and cannot provide timely feedback on the dynamic changes of the slurry.

[0006] (2) Discontinuity: The inability to monitor changes in the composition of the extraction fluid in real time may lead to problems during the extraction process that are not detected in time.

One of the support rods 102 is located on the same vertical line as the liquid outlet 105.

[0030] like Figure 3 As shown, an extraction detection assembly 2 is fixedly connected to the liquid outlet 105. The extraction detection assembly 2 includes an inflow pipe 201, one end of which is fixedly connected to the liquid outlet 105.

[0042] (1) Extraction pump In pipeline liquid testing systems, the extraction pump is extremely important. It is the core power that enables the entire testing process to proceed smoothly. It is responsible for extracting the liquid from the pipeline and providing samples for subsequent testing steps.

[0043] The working principle of a pump is based on the fundamental principles of fluid mechanics in physics. Its core lies in generating a driving force to flow liquid through specific mechanical devices or physical actions. Specifically, a pump utilizes the principle of negative pressure or mechanical force to create a region inside the pump chamber with a pressure lower than that of the liquid inside the pipe, thus generating suction. Under this suction, the liquid overcomes the resistance of the pipe and its own viscosity, flowing from the pipe into the pump chamber, thereby achieving the extraction and transportation of the liquid. For example, a common vacuum pump utilizes the principle of negative pressure, creating a vacuum or negative pressure state inside the pump chamber through mechanical evacuation, drawing liquid into the pump. Some mechanical pumps, such as gear pumps and centrifugal pumps, generate a force on the liquid through the movement of mechanical components, such as the meshing rotation of gears or the high-speed rotation of an impeller, propelling the liquid flow.

[0044] Common types of air pumps include: Gear pumps are a type of positive displacement pump. Their main working component is a pair of meshing gears, typically consisting of a driving gear and a driven gear. When the motor drives the driving gear to rotate, the driven gear rotates synchronously. During the meshing and disengagement of the gears, the volume of the pump chamber changes. On the suction side, the gears gradually disengage, the tooth groove space gradually increases, creating a partial vacuum, and the liquid is drawn into the tooth grooves under atmospheric pressure. As the gears rotate, the liquid is carried to the discharge side, where the gears gradually mesh, the tooth groove space gradually decreases, the liquid is compressed, and thus discharged from the pump chamber. Gear pumps are characterized by their relatively simple and compact structure, high reliability, and ability to transport high-viscosity liquids. They are commonly used in industries such as petrochemicals and machinery manufacturing to transport high-viscosity media such as lubricating oil and fuel oil.

[0045] Centrifugal pumps are pumps that operate by generating centrifugal force through the high-speed rotation of an impeller. A centrifugal pump mainly consists of an impeller, pump casing, shaft, suction chamber, and discharge chamber. When the motor drives the impeller to rotate at high speed, the liquid inside the impeller is thrown towards the outer edge of the impeller under the action of centrifugal force, gaining greater kinetic and pressure energy, and thus discharged from the impeller outlet into the pump casing. At the center of the impeller, due to the liquid being thrown out, a low-pressure zone is formed, and the liquid in the pipeline is drawn into the center of the impeller under atmospheric pressure. This cycle repeats, achieving continuous liquid transportation. Centrifugal pumps have advantages such as large flow rate, simple structure, convenient operation, and stable operation, and are suitable for liquid transportation scenarios requiring large flow rates and low pressure, such as urban water supply, sewage treatment, and agricultural irrigation.

[0046] Plunger pumps: Plunger pumps are reciprocating positive displacement pumps. Their working principle is based on the reciprocating linear motion of a plunger within the pump cylinder. When the plunger moves outward, the pump chamber volume increases, the pressure decreases, and liquid is drawn into the pump chamber through the inlet valve. When the plunger moves inward, the pump chamber volume decreases, the pressure increases, and liquid is discharged from the pump chamber through the outlet valve. Through the continuous reciprocating motion of the plunger, continuous liquid intake and discharge are achieved. The outstanding feature of plunger pumps is their ability to generate high pressure, making them suitable for high-pressure, low-flow-rate liquid transportation needs. They have wide applications in fields such as oil extraction, high-pressure cleaning, and hydraulic systems. For example, in oil drilling, drilling fluid needs to be delivered to the bottom of the well at high pressure, and plunger pumps can effectively meet this requirement.

[0047] In pipeline liquid detection systems, the extraction pump is a crucial bridge connecting the pipeline and the detection equipment. Its primary function is to extract the liquid flowing in the pipeline and deliver it to subsequent detection instruments, such as spectral sensors and conductivity sensors, at a specific flow rate and pressure. This provides these sensors with representative liquid samples, ensuring that the detection results accurately reflect the properties and state of the liquid within the pipeline. The performance parameters of the extraction pump, such as flow rate and pressure, have a significant impact on the efficiency and accuracy of the detection work. Unstable flow rates can lead to fluctuations in the sample volume received by the sensors, affecting the stability and repeatability of the detection data. Conversely, excessively high or low pressures may damage the detection equipment or prevent proper sample delivery, resulting in inaccurate detection results. Therefore, when selecting and using an extraction pump, it is necessary to precisely match its flow rate and pressure parameters according to specific detection requirements and pipeline conditions to ensure the reliable operation of the entire detection system.

[0048] (2) Spectral sensor The fundamental principle of spectral sensors is based on the absorption, emission, and scattering characteristics of matter at different wavelengths. When a beam of light with continuous wavelengths shines on a substance, the atoms, molecules, and other microscopic particles within the substance interact with the light. Because different substances have different atomic and molecular structures, as well as different types and vibrational modes of chemical bonds, their absorption, emission, and scattering behaviors exhibit specificity. For example, some substances strongly absorb light of specific wavelengths because the energy of photons at these wavelengths precisely matches the energy level transitions of the microscopic particles within the substance. After the photons are absorbed, the microscopic particles transition from a lower energy level to a higher energy level. During emission, the excited microscopic particles spontaneously return to a lower energy level, releasing excess energy in the form of light, producing an emission spectrum of a specific wavelength. Scattering occurs when light interacts with matter; due to the inhomogeneity of the substance's internal microstructure, the direction of light propagation changes, and the intensity and wavelength distribution of the scattered light also contain structural information about the substance. Spectral sensors achieve in-depth analysis of the composition, structure, and properties of substances by precisely measuring and analyzing this spectral information generated by light interactions.

[0049] The structure of the spectral sensor is as follows: Light source: The light source is the key device in a spectral sensor that generates light signals. Its function is to provide light signals covering different wavelengths from the ultraviolet to the infrared range to meet various measurement needs. Common light sources include white LEDs, lasers, and gratings. White LEDs emit white light containing multiple color components, and through further processing by optical elements, light of different wavelengths can be obtained. Lasers have the characteristics of high brightness, good monochromaticity, and strong directionality, and can generate laser beams with specific wavelengths and stable intensity, making them suitable for detection scenarios with high requirements for light signal intensity and wavelength accuracy. Gratings utilize the principle of light diffraction to decompose composite light into monochromatic light of different wavelengths, thereby providing the required light signals for spectral analysis.

[0050] Optical path components: Optical path components are mainly used to stably and accurately transmit optical signals to samples or detectors. Common optical path components include lenses, gratings, and optical fibers. Lenses can focus, collimate, and image light, ensuring that the optical signal illuminates the sample at the appropriate angle and intensity. Gratings in the optical path can not only act as beam splitters, decomposing composite light into light of different wavelengths, but also be used for beam shaping and modulation. Optical fibers have excellent optical transmission performance, enabling efficient transmission of optical signals to samples or detectors at long distances, and can be flexibly deployed in various complex detection environments. During optical path design, factors such as transmission distance, wavelength range, and beam quality need to be comprehensively considered to ensure the stability and accuracy of optical signal transmission. For example, for long-distance optical signal transmission, low-loss optical fibers need to be selected, and the connection method and bending radius of the optical fibers need to be designed appropriately to reduce optical signal attenuation. For optical signals within a specific wavelength range, suitable lenses and gratings need to be selected to ensure that dispersion and aberrations during transmission are controlled within acceptable ranges.

[0051] Optoelectronic conversion devices: The function of optoelectronic conversion devices is to convert light signals into electrical signals for subsequent signal processing and analysis. Common optoelectronic conversion devices include photodiodes, photomultiplier tubes, and photodetectors. A photodiode is a photoelectric conversion element based on semiconductor materials. When light shines on the PN junction of a photodiode, electron-hole pairs are generated. Under the influence of an electric field, these electron-hole pairs form a current, thus converting the light signal into an electrical signal. A photomultiplier tube has extremely high sensitivity. It amplifies photoelectrons through multiple dynodes, converting weak light signals into stronger electrical signals, making it suitable for detecting extremely weak light signals. A photodetector is a device that converts light radiation into electrical signals. There are many types of photodetectors. Different types can be selected according to different working principles and application scenarios, such as charge-coupled devices (CCDs) and complementary metal-oxide-semiconductor (CMOS) image sensors. They play an important role in spectral imaging and multi-channel spectral detection.

[0052] Signal processing devices are used to amplify, filter, digitize, and analyze electrical signals after photoelectric conversion, ultimately obtaining the spectral information of the substance. Signal processing devices typically include analog amplifiers, filters, ADCs (analog-to-digital converters), and dedicated chips. Analog amplifiers amplify weak electrical signals to bring them up to the level range that subsequent processing circuits can handle; filters remove noise and interference from the electrical signals, improving signal quality; ADCs convert continuous analog electrical signals into discrete digital signals for computer processing and storage; and dedicated chips integrate various digital signal processing algorithms and functional modules, enabling rapid and accurate analysis and processing of digitized spectral data, such as spectral calibration, noise reduction, feature extraction, and quantitative analysis.

[0053] The working process of a spectral sensor is as follows: Optical signal generation: The spectral sensor first uses a light source to generate optical signals with different wavelengths. These light sources can provide light covering the range from ultraviolet to infrared. For example, a common white LED can generate composite light containing multiple color components. After passing through a spectrometer, monochromatic light signals of different wavelengths can be obtained. Lasers can generate laser beams with specific wavelengths and stable intensity, providing a high-quality optical signal source for spectral detection.

[0054] Optical signal transmission: The generated optical signal is transmitted through carefully designed optical path devices, typically using lenses, gratings, or optical fibers. Lenses are used for focusing and collimating the optical signal, ensuring that the signal illuminates the sample at the appropriate angle and intensity. Gratings can decompose composite light into monochromatic light of different wavelengths, achieving spectral separation. Optical fibers can efficiently transmit the optical signal to samples or detectors at long distances and can flexibly adapt to various complex detection environments. In optical path design, factors such as transmission distance, wavelength range, and beam quality must be fully considered to ensure that the optical signal is transmitted stably and accurately to the sample or detector.

[0055] Optical signal conversion: The light signal transmitted to the sample or detector interacts with the substances in the sample, such as absorption, reflection, transmission, and scattering. Different substances, due to their different compositions and structures, interact with light in different ways. For example, some substances absorb light of specific wavelengths, causing a decrease in the intensity of that wavelength; while other substances scatter light, changing the direction of light propagation. These altered optical signals are guided to photoelectric conversion devices and converted into electrical signals. For example, a photodiode generates a current when illuminated, the magnitude of which is proportional to the intensity of the light, thus realizing the conversion of optical signals into electrical signals.

[0056] Optical signal processing: The electrical signal converted by the photoelectric conversion device needs to be amplified, filtered, digitized, and analyzed by signal processing devices. First, the analog amplifier amplifies the weak electrical signal to a level that can be processed by subsequent processing circuits; then, the filter removes noise and interference from the electrical signal, improving signal quality; next, the ADC converts the continuous analog electrical signal into discrete digital signals; finally, a dedicated chip analyzes and processes the digitized spectral data. Through specific data processing algorithms, these spectral data can be denoised, corrected, and quantitatively analyzed to obtain information such as the composition, structure, properties, or concentration of the analyte.

[0057] In pipeline liquid inspection, spectral sensors analyze the spectral information of liquids to accurately detect key parameters such as liquid composition, concentration, and purity. Different liquid components possess unique spectral characteristics, much like each person has a unique fingerprint. For example, various ions, organic matter, and dissolved gases in water produce absorption or emission peaks at specific wavelengths. By accurately measuring these spectral characteristics and comparing them with known standard spectral databases, spectral sensors can accurately identify the various substances present in the liquid. When inspecting liquids in petrochemical pipelines, spectral sensors can quickly detect the types and contents of hydrocarbon compounds, providing crucial information for quality control in the production process. By analyzing changes in the intensity of spectral signals, spectral sensors can also quantitatively determine the concentration of each component in the liquid. When the concentration of a component exceeds the normal range, the system can promptly issue an alarm, reminding personnel to take appropriate measures to ensure the safety and stability of the production process. Spectral sensors can also be used to detect liquid purity. By detecting the characteristic signals of impurities in the spectrum, the content of impurities in the liquid can be determined, thereby assessing whether the liquid's purity meets requirements.

[0058] (3) Conductivity sensor Conductivity sensors are used to measure the conductivity of solutions, providing insights into the solution's electrical conductivity and ion concentration.

[0059] Electrical conductivity, from a physical definition, refers to the ability of a conductor to conduct electric current per unit cross-sectional area and unit length, and its unit is Siemens per meter (S / m). In solution systems, conductivity reflects the conductivity of ions in the solution and is an important indicator for measuring ion concentration and ion mobility. When various ions are present in a solution, these ions can move directionally under the influence of an electric field, thus forming an electric current, and the solution possesses the ability to conduct electricity. A conductivity sensor is a device specifically designed to accurately measure this physical quantity. It can convert the conductivity value of a solution into a readable and analyzable electrical or digital signal, providing data support for subsequent research and applications. For example, in the production process of purified water, the content of ionic impurities in the water can be monitored in real time through conductivity sensor detection, thereby ensuring that the produced purified water meets quality standards. Because purified water contains almost no conductive ions, its conductivity is extremely low. If the detected conductivity increases, it means that other ionic impurities have been introduced into the water, which may affect the purity and performance of the water.

[0060] The working principle of a conductivity sensor is closely based on the ion conduction characteristics of a solution. Its core component typically consists of two or more electrodes made of metals (such as platinum, titanium, etc.) or graphite. When these electrodes are inserted into the solution to be measured, a closed circuit system is formed. In this system, the signal processing circuit inside the sensor applies a certain DC or AC voltage to a pair of electrodes, generating an electric field in the solution. Under the influence of this electric field, positive and negative ions in the solution are driven by the electric force to move in opposite directions: positive ions move towards the negative electrode, and negative ions move towards the positive electrode. This directional movement of ions forms a current. According to Ohm's law (I=V / R), current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R). In conductivity measurement, the conductivity of the solution can be indirectly reflected by measuring the current intensity flowing through the circuit. Because resistance is inversely proportional to conductivity, the conductivity of the solution can be calculated using a formula by combining known parameters such as electrode spacing and cross-sectional area (which determine the electrode constant). In practical applications, the conductivity of a solution is significantly affected by temperature. Generally, the conductivity of a solution increases with increasing temperature. Therefore, conductivity sensors typically incorporate calibration coefficients and temperature compensation functions to ensure accurate and reliable measurement results under varying temperature conditions. For example, in monitoring industrial circulating water, ambient temperature may change. Without temperature compensation, the measured conductivity data will be inaccurate and fail to accurately reflect the actual ion concentration in the water. Temperature compensation allows the sensor to correct the conductivity measurement results based on real-time temperature data, providing more accurate monitoring data and strong support for the control and optimization of industrial production processes.

[0061] Conductivity sensors mainly include the following types: Electrode-type conductivity sensors: These sensors measure conductivity using a resistance measurement method based on the principle of electrolytic conduction. The conductivity measuring electrode behaves as a complex electrochemical system during the measurement process. The two-electrode conductivity sensor is the most basic type, consisting of a pair of electrodes. In actual measurement, a constant voltage is applied to these electrodes. As the resistance of the liquid in the conductivity cell changes, the current in the measuring electrode also changes accordingly, and this change obeys Ohm's law. By replacing resistivity with conductivity, and resistance in the metal with conductance, the conductivity of the liquid can be measured. However, when measuring conductivity with two electrodes, under the action of the excitation voltage, the electrodes electrolyze the solution, thus forming a potential on the electrode surface opposite to the direction of the applied voltage. This increases the equivalent resistance of the measured solution, leading to polarization and causing measurement deviations. To solve this problem, the four-electrode conductivity sensor was developed. The four-electrode conductivity sensor utilizes two pairs of coaxial current electrodes and voltage electrodes. During the measurement process, two pairs of electrodes are placed in the solution to be measured. An AC signal is applied to the current electrodes, and the current on the current electrodes is transmitted to the solution, generating an electric field. At this time, the two voltage electrodes will induce voltages, and the circuit design ensures that the voltage across the voltage electrodes remains constant. Since the current between the current electrodes has a linear relationship with the liquid conductivity, the conductivity of the solution can be accurately calculated by measuring the current between the current electrodes. This design effectively avoids the polarization effect of the two electrodes, improving the accuracy and stability of the measurement. It is particularly suitable for solutions with high conductivity and applications requiring high measurement accuracy, such as water quality monitoring in industrial wastewater treatment and precise measurement of seawater salinity.

[0062] Inductive conductivity sensors measure the conductivity of liquids based on the principle of electromagnetic induction. Their unique structure resembles a pair of transformer coils, with the solution being measured acting as the transformer's core. Two sets of coils are wound around the sensor: one for transmitting and the other for receiving. These coils are parallel, compact, and insulated from each other, and are housed within a ring-shaped polymer core immersed in the solution. When alternating current is applied to the transmitting end, an alternating magnetic field is generated in the solution. This alternating magnetic field induces an electromotive force (EMF) in the receiving coil. According to the principle of electromagnetic induction, the magnitude of this EMF is directly proportional to the conductivity of the solution. Therefore, by accurately measuring the intensity of the induced signal in the receiving coil, the conductivity value of the liquid can be indirectly obtained. Inductive conductivity sensors offer many significant advantages. Because the detector does not directly contact the liquid being measured, there are no issues of electrode polarization or contamination. This gives them strong resistance to contamination and corrosion, allowing them to operate stably in harsh measurement environments. Its measurement range is typically 1,000-2,000,000 μS / cm, making it particularly suitable for measuring liquids with high conductivity, such as measuring the concentration of strong acids and bases in chemical production, and for precise analysis of seawater salinity in marine development and research.

[0063] Ultrasonic conductivity sensors measure conductivity based on changes in the propagation characteristics of ultrasonic waves in liquids. The speed and attenuation of ultrasonic waves propagating in a liquid are affected by the liquid's conductivity. The sensor emits ultrasonic waves and receives their reflected or transmitted signals, then analyzes these signal changes to calculate the liquid's conductivity. This measurement method offers significant advantages such as being non-contact and free of electrode contamination, making it suitable for applications with demanding environmental requirements where traditional electrode-based sensors are inconvenient. For example, in measuring the conductivity of high-temperature, high-pressure, and highly corrosive liquids, ultrasonic conductivity sensors offer unique advantages, ensuring safe and reliable measurement. In certain specialized chemical production processes, where conductivity monitoring of highly corrosive reaction solutions is necessary, ultrasonic conductivity sensors avoid the corrosion caused by direct electrode contact with the solution, while also ensuring the accuracy and timeliness of the measurement data.

[0064] Conductivity sensors play a crucial role in pipeline liquid monitoring. By measuring the conductivity of liquids in pipelines, key information about the ion concentration in the liquid can be obtained. In industrial production, many chemical reactions depend on specific ion concentration conditions. If the ion concentration of the reaction liquid in the pipeline changes abnormally, it may prevent the chemical reaction from proceeding normally, affecting product quality and even production safety. Real-time monitoring of ion concentration by conductivity sensors allows for timely detection of problems and corresponding adjustments, ensuring the stability and efficiency of the production process. Conductivity sensors can also be used to determine the purity of liquids. In industries with extremely high requirements for liquid purity, such as pharmaceuticals and electronics, even tiny impurity ions can seriously affect product performance. For example, in the manufacturing process of electronic chips, if the ultrapure water used contains too many ionic impurities, it may cause short circuits or other performance failures in the chips. By detecting the conductivity of water, the content of ionic impurities in the water can be accurately determined, thereby ensuring that the water used meets purity requirements. Conductivity sensors can also help detect the degree of contamination in liquids. In the environmental protection field, there are strict standards for the discharge of industrial wastewater and domestic sewage. By measuring the conductivity of sewage, we can roughly understand the total amount of dissolved solids, including various salts, minerals, and potential pollutants, providing an important basis for assessing the degree of sewage pollution and developing corresponding treatment plans. At sewage treatment plants, by monitoring the changes in the conductivity of sewage before and after treatment, we can directly judge the effectiveness of the treatment process and adjust treatment parameters in a timely manner to achieve better sewage treatment results and reduce environmental pollution.

[0065] (4) Pressure sensor A pressure sensor is a device that can accurately sense pressure signals and convert them into usable output electrical signals according to specific rules.

[0066] The basic principle of pressure sensors is based on the deformation or change in properties of a specific material caused by pressure, which in turn generates an electrical signal. The most common principle is the strain effect. The strain effect refers to the change in shape and size of a material when subjected to external force, leading to changes in its resistance or other electrical properties. Taking a metal strain gauge as an example, when a metal wire is stretched or compressed, its length and cross-sectional area change. According to the law of resistance (R=ρL / S, where R is resistance, ρ is resistivity, L is length, and S is cross-sectional area), the resistance value changes accordingly. For semiconductor materials, under pressure, the concentration and mobility of charge carriers inside change, resulting in a more significant change in resistance. Pressure sensors based on semiconductor materials are called piezoresistive pressure sensors, widely used in practical applications due to their high sensitivity and accuracy. Besides the strain effect, piezoelectric and capacitive effects are also used in pressure sensor design. The piezoelectric effect refers to the generation of electric charge in certain materials when subjected to pressure. By measuring the magnitude of the charge, the pressure value can be indirectly obtained. The capacitance effect utilizes the change in the distance between the plates or the dielectric constant of a capacitor caused by pressure, thereby changing the capacitance value, and thus measuring the pressure.

[0067] The pressure sensor mainly consists of the following structure: Pressure sensor: Also known as a sensitive element, the pressure sensor is the core component of a pressure sensor. It comes into direct contact with an external pressure source and exhibits a strain effect when subjected to external pressure. Common pressure sensor materials include silicon, metal thin films, and quartz crystals. Silicon, due to its excellent mechanical and electrical properties, is widely used in modern pressure sensors. High-precision pressure-sensitive structures can be fabricated on silicon wafers using microelectromechanical systems (MEMS) technology. Metal thin film pressure sensors offer good stability and reliability, making them suitable for applications where accuracy requirements are relatively low but stability is paramount. Quartz crystals, due to their unique piezoelectric properties, are commonly used to manufacture piezoelectric pressure sensors, enabling rapid response to dynamic pressure changes. Pressure sensors come in various shapes and structures, including flat diaphragms, corrugated diaphragms, cylindrical shapes, thin-walled cylindrical shapes, and beam shapes. Flat diaphragms have a simple structure, are easy to manufacture, and are suitable for general pressure measurement applications; corrugated diaphragms have a large range of elastic deformation and can withstand large pressures, and are often used for high-pressure measurements; cylindrical and thin-walled cylindrical structures have good mechanical properties when subjected to axial pressure and are suitable for some special pressure measurement needs; beam structures are more sensitive to small pressure changes and are often used in high-precision pressure testing equipment.

[0068] Support Structure: The support structure plays a crucial role in the stability and force transmission of pressure sensors. It maintains the stability of the pressure sensor, ensuring it accurately generates strain when subjected to pressure and uniformly and effectively transmits the applied pressure to the sensing element. Support structures are typically made of robust materials such as metals and ceramics to guarantee reliable operation in various complex working environments. In some high-precision pressure sensors, the design of the support structure requires precise mechanical analysis and optimization to minimize the impact of deformation on pressure measurement results. For example, pressure sensors used in the aerospace field must not only withstand the various mechanical loads generated during flight but also ensure the pressure sensor functions normally under extreme temperature and vibration conditions, thereby guaranteeing the accuracy and reliability of pressure measurements.

[0069] Signal Converter: The main function of the signal converter is to convert the strain signal generated by the pressure sensor into an electrical signal that is easy to measure and process. In pressure sensors, the most common signal conversion method is using a Wheatstone bridge circuit. Taking a Wheatstone bridge as an example, it consists of four resistors: two fixed resistors and two variable resistors connected to the pressure sensor. When pressure is applied to the pressure sensor, the resistance of the variable resistors changes, thus disrupting the balance of the bridge and causing it to output a voltage signal proportional to the pressure. Besides bridge circuits, there are other signal conversion methods, such as using the piezoelectric effect of piezoelectric materials to directly convert pressure into a charge signal, and then using a charge amplifier to convert the charge signal into a voltage signal; or using the capacitance effect to convert the capacitance change caused by pressure into an electrical signal. In practical applications, the appropriate signal conversion method and circuit structure are selected based on the working principle and performance requirements of the pressure sensor.

[0070] Output Interface: The output interface is the key channel for communication and data transmission between the pressure sensor and external devices. Its function is to transmit the converted electrical signal to external devices such as displays, control systems, and data acquisition cards. Common output interface types include analog signal output interfaces (such as voltage output and current output) and digital signal output interfaces (such as SPI interface, I2C interface, and RS485 interface). Analog signal output interfaces have the advantages of simple structure and low cost, but their anti-interference capability is relatively weak, and the signal transmission distance is limited. Digital signal output interfaces, on the other hand, have advantages such as strong anti-interference capability, fast transmission speed, high accuracy, and easy integration with digital systems, and are widely used in modern intelligent pressure detection systems. In some industrial automation control systems, the pressure sensor is connected to a programmable logic controller (PLC) via an RS485 interface, transmitting real-time measured pressure data to the PLC. The PLC then uses this data to precisely control the production process. In smart IoT devices, the pressure sensor can transmit data to a cloud server via wireless communication interfaces (such as Wi-Fi, Bluetooth, and ZigBee) to achieve remote monitoring and management.

[0071] The working process of the pressure sensor is as follows: Pressure Sensing: When external pressure is applied to a pressure sensor, the pressure sensor directly bears the pressure first. Pressure sensors are typically made of materials with good elasticity, such as silicon or thin metal films. These materials undergo minute deformation or elastic deformation when subjected to pressure. For example, when pressure is applied to a silicon-based pressure sensor, the silicon material will undergo minute bending or tensile deformation under the pressure. This deformation is the initial step in the operation of the pressure sensor, converting the external pressure signal into the physical deformation of the pressure sensor.

[0072] Strain generation: When a pressure sensor deforms, its internal atomic structure undergoes minute displacements. Taking metallic materials as an example, the spacing between atoms changes, leading to a shift in the electron cloud distribution and consequently altering the material's electrical resistance. For semiconductor materials, pressure distorts the atomic lattice structure, affecting the movement and distribution of charge carriers, resulting in changes in carrier concentration and mobility, and thus significantly altering the semiconductor's electrical properties. These changes in the material's electrical properties caused by pressure constitute the strain signal, which contains information such as the magnitude and direction of the external pressure.

[0073] Strain Signal Conversion: Strain signals are typically very weak and require amplification and processing by a signal converter for subsequent measurement and control. A common signal converter is a bridge circuit, such as the Wheatstone bridge. In a Wheatstone bridge, the resistor connected to the pressure sensor acts as a variable resistor. When pressure causes a change in resistance, the bridge's balance is disrupted, outputting a voltage signal proportional to the pressure. This voltage signal is further amplified by an amplifier to increase its amplitude, making it suitable for subsequent processing circuits. During amplification, the signal is also filtered to remove noise and interference, improving signal quality.

[0074] Output and Display: The amplified and processed voltage signal is transmitted to the output interface. The output interface can transmit the signal to external devices in either analog or digital form. In digital systems, analog-to-digital conversion (ADC) is typically performed to convert the analog signal into a digital signal. Ultimately, these signals can be used for feedback in the control system to achieve precise pressure control; they can also be used for data recording, providing a basis for subsequent data analysis and processing; or they can be displayed on a screen for operators to observe intuitively and understand pressure changes in a timely manner. On industrial automated production lines, pressure sensors transmit pressure data to the control system, which adjusts the operating parameters of the production equipment based on the pressure data to ensure stable production and qualified product quality. In laboratories, pressure sensor data can be recorded for scientific research and experimental data analysis.

[0075] Pressure sensors play an indispensable role in pipeline liquid monitoring. They monitor the pressure of the liquid within the pipeline in real time, providing crucial pressure data for the entire monitoring system. Accurate measurement of the liquid pressure within the pipeline ensures that it operates within a safe pressure range, preventing accidents such as pipeline rupture and leakage due to excessive pressure, or disruptions to normal liquid transport and process flows due to insufficient pressure. In oil pipelines, pressure sensors constantly monitor the oil pressure. Once the pressure exceeds a set safety threshold, the system immediately issues an alarm and takes corresponding pressure-reducing measures to ensure safe pipeline operation. Furthermore, pressure data provides important reference for the analysis and judgment of other detection parameters. When analyzing the flow rate of liquid within a pipeline, combining the pressure data measured by the pressure sensor with information such as the pipeline's geometric parameters, the flow rate can be calculated using relevant fluid dynamics formulas, thus achieving indirect measurement of the liquid flow rate. Pressure sensors can also be used to detect blockages, leaks, and other faults within the pipeline. When a pipeline becomes blocked, the pressure upstream of the blockage point will increase. Once the pressure sensor detects the abnormal increase in pressure, it can determine that there may be a blockage in the pipeline and promptly notify staff to investigate and clean it. When a pipeline leaks, the pressure near the leak point will decrease. By monitoring the pressure changes through the pressure sensor, the leak location can be quickly located, reducing the impact of liquid leakage on the environment and production.

[0076] (5) Temperature sensor Temperature sensors mainly include the following categories: Thermocouples: Thermocouples are temperature sensors that operate based on the Seebeck effect. They consist of two different metal or alloy wires, welded together at one end to form the measuring junction, and the other end to serve as the reference junction. When a temperature difference exists between the measuring and reference junctions, a thermoelectric potential is generated between the two metals. This thermoelectric potential is directly proportional to the temperature difference. For example, if one end of a nickel-chromium alloy wire and the other end of a nickel-silicon alloy wire are welded together, a thermoelectric potential will be generated in the circuit when the temperature of the welded end (measuring junction) is higher than that of the other end (reference junction). By measuring this thermoelectric potential and referring to a pre-calibrated thermoelectric potential-temperature correspondence table (calibration table), the temperature of the measuring junction can be accurately calculated. Thermocouples have advantages such as simple structure, wide measurement range (measuring temperatures from -200℃ to 2800℃), and fast response speed, and are widely used in industrial production, metallurgy, and power industries.

[0077] Thermistors: A thermistor is a sensitive element whose resistance changes significantly with temperature. Based on this characteristic, they can be divided into positive temperature coefficient (PTC) thermistors and negative temperature coefficient (NTC) thermistors. PTC thermistors exhibit increased resistance with increasing temperature. Made primarily of barium titanate with added rare earth elements, PTC thermistors have low resistance at room temperature. However, when the temperature rises to a critical temperature (e.g., 120°C), their internal electric field structure changes, causing a sharp increase in resistance. This characteristic makes them commonly used in overheat protection circuits, such as in motors and transformers. When the temperature is too high, the increased resistance of the PTC thermistor limits the current, protecting the equipment. NTC thermistors, on the other hand, exhibit decreased resistance with increasing temperature. They are typically made from metal oxides such as manganese oxide, cobalt oxide, and nickel oxide using ceramic processing techniques. Because these metal oxides possess semiconductor properties, the number of charge carriers increases with increasing temperature, leading to a decrease in resistance. NTC thermistors are highly sensitive and have a fast response speed, making them widely used in temperature measurement and temperature compensation fields, such as in household appliances like air conditioners and refrigerators, where they are used as temperature probes to monitor the temperature of the environment or medium in real time.

[0078] Semiconductor temperature sensors measure temperature by utilizing the principle that the resistance or voltage characteristics of semiconductor materials change with temperature. In semiconductor materials, the voltage drop across a PN junction changes with temperature. As temperature increases, the voltage drop decreases; conversely, as temperature decreases, the voltage drop increases. By accurately measuring the voltage drop across the PN junction and applying a pre-calibrated voltage-temperature relationship, the current temperature can be calculated. For example, in some electronic devices, the temperature characteristics of diodes or transistors are used to measure temperature. Under constant current, the forward voltage of a diode decreases as temperature increases; by measuring the change in the forward voltage of the diode, the temperature change can be deduced. Semiconductor temperature sensors offer advantages such as high accuracy, good linearity, and small size, and are commonly used in applications requiring high temperature measurement accuracy, such as medical equipment and precision instruments.

[0079] Infrared temperature sensors measure temperature based on the infrared radiation characteristics of objects. In nature, any object with a temperature above absolute zero (-273.15℃) will radiate infrared radiation, and the intensity and spectral characteristics of this radiation are closely related to the object's temperature. Infrared temperature sensors receive the infrared radiation emitted by an object, convert it into an electrical signal, and then calculate the object's temperature according to the Stefan-Boltzmann law (radiation intensity is proportional to the fourth power of temperature) and Wien's displacement law (peak wavelength of radiation is inversely proportional to temperature). It typically includes an optical system that focuses infrared radiation onto a detector, which converts the infrared radiation into an electrical signal. After processing by a signal processing circuit, the temperature value of the object is output. Infrared temperature sensors have advantages such as non-contact measurement, fast response speed, and wide measurement range. They can be used to measure the temperature of high-temperature, moving, or inaccessible objects, playing a crucial role in high-temperature furnace temperature monitoring in industrial production, overheat detection of electrical equipment, and human body temperature detection during pandemics.

[0080] In pipeline liquid monitoring, temperature sensors play an indispensable role. Accurately measuring the temperature of liquids within pipelines provides crucial clues for understanding their physical properties. The viscosity, density, and chemical reaction rate of liquids are often closely related to temperature. In petrochemical production, the viscosity of crude oil decreases with increasing temperature. By monitoring the temperature of crude oil within pipelines, its flow properties can be predicted, providing a basis for optimizing transportation processes. Temperature data also provides important references for other detection parameters. When measuring the conductivity of liquids, temperature has a significant impact. Temperature compensation based on temperature data measured by temperature sensors can improve the accuracy of conductivity measurements. In some chemical reactions, temperature changes can affect the reaction process and the quality of the products. Real-time monitoring of the reaction liquid temperature within pipelines allows for timely adjustments to reaction conditions, ensuring smooth reaction progress and stable product quality.
