When the temperature changes, the different thermal expansion of the two metals causes the pointer to deflect, indicating the temperature. This is the bimetallic thermometer. Modern bimetallic thermometers are all single-measurement thermometers. For different work requirements, there may be a need to measure temperature differences in different environments, such as the temperature difference between the inside and outside of a pipe.

The recoil signal is then subjected to a 90-degree phase flip and superimposed with the compressed coding block and M compressed error correction and verification packets to generate an electromagnetic adaptation correction signal. If the determination result is a noise interference scenario, then the high-frequency channel is acquired, the difference signal between the test signal and the standard signal is extracted, and the difference signal is low-pass filtered to generate a noise suppression and correction signal.

The pointer shaft is sleeved on the other end of the rotating shaft. The pointer is connected to the pointer at the end of the pointer shaft away from the rotating shaft. A limiting block is located above the rotating shaft. A slider is located on the inner wall of the limiting block. A groove that matches the slider is formed on the outer circumferential surface of the pointer shaft.

[0008] Furthermore, the adjustment assembly includes a slot one, a spring, a locking head, and a slot two. The sleeve rod has a slot two on its wall surface, and the movable rod has a slot one corresponding to slot two on its side. The locking head is placed inside slot one, and a spring is fixedly installed inside slot one. The other end of the spring is connected to the locking head. By locking the movable rod into or popping out slot two, the length between the movable rod and the sleeve rod is locked and adjusted. The inner wall of slot two has pairs of symmetrically distributed pressing columns. The pressing columns have guide slopes. When the movable rod moves telescopically relative to the sleeve rod, the pressing columns slide along the end of the locking head and fall into different slots two with the help of the spring.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] To address the technical issue that existing bimetallic thermometers are all single-measurement thermometers, which may require measuring temperature differences in different environments for various work needs, thus necessitating separate measurements at different locations and causing inconvenience, please refer to [link to relevant documentation]. Figures 1-7 This embodiment provides the following technical solution: A bimetallic thermometer capable of measuring temperature difference includes a dial 1 with two scales, each corresponding to a temperature measuring unit and equipped with an independent pointer 4, capable of displaying two different temperature values ​​simultaneously. Symmetrically arranged on both sides of the dial 1 are sleeves 2, with a movable rod 3 fitted onto the other end of each sleeve. An adjustment component 5 is provided on the movable rod 3, allowing for length adjustment between the sleeves 2 and the movable rod 3. Inside the movable rod 3 is a bimetallic strip 32 for sensing temperature changes. The bimetallic strip 32 is the key temperature-sensing element of the bimetallic thermometer, composed of two metal strips with different coefficients of thermal expansion tightly bonded together. When the temperature changes, the bimetallic strip 32 bends and deforms due to the different degrees of expansion of the two metal strips. This deformation is transmitted to the pointer 4 through a mechanical transmission structure, thereby driving the pointer 4 to move on the scale and display the corresponding temperature value.

[0020] The technical effects of the above solution are as follows: First, the dial 1 is equipped with a double scale, and each scale corresponds to a temperature measuring unit and is equipped with an independent pointer 4. It can simultaneously measure and display the temperature values ​​of two different locations or different objects, providing users with richer temperature information and meeting the needs of comparing two temperatures simultaneously in some special situations. Second, the length adjustment function of the sleeve rod 2 and the movable rod 3 greatly improves the applicability and flexibility of the thermometer. Whether in a narrow environment with limited space or in situations where it is necessary to measure objects at a distance, the length of the movable rod 3 can be adjusted to adapt to the situation, making the bimetallic thermometer easier to install and use, and improving the convenience of measurement and work efficiency.

[0021] The movable rod 3 includes a temperature-conducting head 31, a bimetallic strip 32, a rotating shaft 33, and a pointer shaft 34. The end of the movable rod 3 away from the sleeve rod 2 is provided with a temperature-conducting head 31. The temperature-conducting head 31 is made of a material with high thermal conductivity, which can quickly absorb the heat of the object being measured and transfer it to the bimetallic strip 32. The movable rod 3 is provided with a bimetallic strip 32 inside. One end of the bimetallic strip 32 is connected to the temperature-conducting head 31, so that the bimetallic strip 32 can sense the temperature change transmitted by the temperature-conducting head 31 in time. The other end of the bimetallic strip 32 is connected to the rotating shaft 33. The other end of the rotating shaft 33 is sleeved with a pointer shaft 34. The pointer 4 is connected to the end of the pointer shaft 34 away from the rotating shaft 33. Through this mechanical transmission structure, the rotation of the rotating shaft 33 will drive the pointer shaft 34 to rotate, thereby driving the pointer 4 to move on the scale to display the corresponding temperature value. The technical effect of the above technical solution is as follows: When the temperature conducting head 31 of the thermometer comes into contact with the object being measured, the temperature conducting head 31 will quickly absorb the heat of the object being measured, thereby quickly transferring the heat to the bimetallic strip 32 connected to it. When the temperature changes, the bimetallic strip 32 will bend and deform due to the different expansion degrees of the two metal strips. This bending and deformation will drive the rotating shaft 33 connected to it to rotate. The rotation of the rotating shaft 33 will further drive the pointer shaft 34 to rotate, thereby driving the pointer 4 to move on the scale and thus display the corresponding temperature value.

[0022] The adjustment component 5 includes a slot 1 51, a spring 52, a locking head 53, and a slot 2 54. The sleeve rod 2 has a slot 2 54 on its wall surface, and the movable rod 3 has a slot 1 51 on its side corresponding to the slot 2 54. The locking head 53 is placed inside the slot 1 51, and the spring 52 is fixedly installed inside the slot 1 51. The other end of the spring 52 is connected to the locking head 53. The elasticity of the spring 52 can ensure that the locking head 53 can be stably engaged in the slot 2 54 at different positions. By locking the locking head 53 into or popping out of the slot 2 54, the length between the movable rod 3 and the sleeve rod 2 can be locked and adjusted. The inner wall of the slot 54 is provided with a pair of extrusion columns 55 that are symmetrically distributed vertically. The extrusion columns 55 have guide slopes. When the movable rod 3 moves in extension and retraction relative to the sleeve rod 2, the extrusion columns 55 slide along the end of the clamp 53 and fall into different slots 54 with the cooperation of the spring 52.

[0023] A limiting block 35 is provided above the rotating shaft 33, and a slider 37 is provided on the inner wall of the limiting block 35. A groove 36 that matches the slider 37 is provided on the outer circumferential surface of the pointer shaft 34. The above design plays a role in limiting and guiding.

[0024] The technical effect of the above solution is as follows: When it is necessary to adjust the length between the movable rod 3 and the sleeve rod 2, an external force is applied to make the movable rod 3 extend and retract relative to the sleeve rod 2. At this time, the pair of extrusion columns 55 on the inner wall of the slot 2 54 slide along the end of the clamp 53. Through the extrusion column 55 extruding the clamp 53 and under the elastic action of the spring 52, the clamp 53 can be smoothly ejected into the slot 2 54. After adjusting to a suitable length, the clamp 53 is pushed into the slot 2 54 by the spring 52. Through the above design, the length between the movable rod 3 and the sleeve rod 2 can be adjusted and locked. Thus, the distance between the two temperature measuring ends can be flexibly adjusted according to the actual distance between the measuring points, so that the bimetallic thermometer can adapt to various complex measurement scenarios and greatly expand the application range of the bimetallic thermometer. During the length adjustment process, the slider 37 moves synchronously in the slide groove 36 so that the rotating shaft 33 and the pointer shaft 34 can adapt to different length adjustments.

[0025] The bimetallic thermometer capable of measuring temperature difference also includes a data acquisition module, a data analysis module, and a result display module; The data acquisition module is configured to capture the mechanical deformation signals of the bimetallic sheets 32 on both sides through deployed electronic sensors and convert them into electrical signals; The data analysis module is configured to process electrical signals, including amplification, filtering and analog-to-digital conversion, to obtain digital temperature signals, and finally obtain the real-time temperature values ​​of the two environments. Based on the temperature values, the temperature difference between the two environments is calculated, and the temperature difference is compared with a preset threshold to determine whether the current temperature difference is abnormal. The result display module is configured to display the temperature difference calculated by the data analysis module on the LCD screen on the dial 1. At the same time, when the temperature difference exceeds a preset threshold, an alarm is triggered by a buzzer on the dial 1.

[0026] The technical effects of the above solution are as follows: The data acquisition module captures the mechanical deformation signal of the bimetallic strip 32 through electronic sensors and converts it into an electrical signal, realizing real-time and accurate measurement of the ambient temperature on both sides. This high-precision signal acquisition and conversion mechanism ensures the accuracy and reliability of the temperature data, providing data support for subsequent data analysis. The data analysis module amplifies, filters, and performs analog-to-digital conversion on the acquired electrical signal, improving the signal quality and stability, thereby obtaining an accurate digital temperature signal and accurately acquiring the real-time temperature values ​​of the ambient environment on both sides. In addition, the temperature difference between the ambient environments on both sides is calculated based on the temperature value, providing a scientific basis for subsequent anomaly judgment. The data analysis module then compares the calculated temperature difference with a preset threshold, which can quickly determine whether there is an anomaly in the current temperature difference, ensuring that users can promptly detect potential safety hazards or equipment failures. The result display module displays the temperature difference on the LCD screen on the dial 1, providing users with intuitive temperature information. At the same time, when the temperature difference exceeds the preset threshold, an alarm is sounded through the buzzer on the dial 1, promptly notifying the user to take appropriate measures.

[0027] The data analysis module includes: The signal processing module is configured to amplify, filter, and perform analog-to-digital conversion on electrical signals, specifically: Use an operational amplifier to amplify a weak signal to a level suitable for analog-to-digital conversion; After amplification, a low-pass filter is used to remove high-frequency noise and interference signals; After filtering, the electrical signal is converted into a digital temperature signal using an analog-to-digital converter. The temperature difference calculation module is configured to convert the preprocessed digital temperature signal into specific temperature values, namely... and This allows us to obtain the real-time temperature values ​​of both sides of the environment. Based on these temperature values, a difference calculation method is used to calculate the temperature difference. ; The anomaly detection module is configured to pre-set thresholds based on the operating requirements and safety standards of the device under test. ,in, For the minimum allowable temperature difference, The calculated temperature difference is the maximum allowable temperature difference. With preset threshold The comparison is as follows: like If the temperature difference is within the allowable range, continue the temperature measurement work. like or If the temperature difference exceeds the allowable range, it is determined that the current temperature difference is abnormal and an early warning mechanism is triggered, which is then used by the result display module to issue an alarm.

[0028] The technical effects of the above solution are as follows: The signal processing module effectively eliminates errors and interference in signal transmission and processing through multi-level processing of amplification, filtering, and analog-to-digital conversion, providing a high-quality data foundation for subsequent temperature difference calculation and anomaly judgment. The temperature difference calculation module ensures the accuracy and reliability of temperature difference data through the difference calculation method. Users can monitor the temperature changes of the two sides of the environment in real time, promptly detect potential temperature anomalies, and enhance the monitoring capability and early warning function of the bimetallic thermometer. The anomaly judgment module, based on the anomaly judgment mechanism of preset thresholds, can quickly and accurately identify whether the temperature difference exceeds the normal range, thereby promptly detecting potential safety hazards or equipment failures and avoiding equipment damage or safety accidents caused by temperature anomalies.

[0029] The results display module includes: The numerical display module is configured to format the temperature difference data calculated by the data analysis module into a displayable format and display it on the LCD screen on dial 1. The alarm reminder module is configured to trigger an alarm reminder when the temperature difference exceeds a preset threshold, driving the buzzer to emit an alarm sound. At the same time, users can set the frequency, duration and volume of the alarm sound through an external input device.

[0030] It also provides data storage functionality, configured to format the calculated temperature values ​​and temperature difference data of both sides of the environment into a unified data structure and store the formatted data. Simultaneously, it establishes a connection with external devices (such as mobile phones, tablets, computers, or cloud servers) via wireless communication to transmit the stored data to the external devices. Specifically, it employs the following transmission methods: While data is being collected and stored, it is transmitted to external devices in real time. Periodically transmit data in batches to external devices within a certain time period; Based on the user's needs, a request is sent through an external device, triggering data transmission.

[0031] The technical effects of the above solution are as follows: The numerical display module displays the temperature difference on the LCD screen of dial 1, allowing users to intuitively obtain information about the temperature difference between the two environments, improving the ease of use and information transparency of the device. When the temperature difference exceeds a preset threshold, the alarm module triggers an alarm, which drives the buzzer to emit an alarm sound. Simultaneously, users can set the frequency, duration, and volume of the alarm sound via external input devices, providing a high degree of customization. The alarm module not only ensures that users receive timely alerts for abnormal temperatures but also meets the needs and preferences of different users through flexible customization settings. Furthermore, the data storage function, through a unified data structure, can efficiently store and manage large amounts of temperature data, improving data availability and reliability. This allows users to query historical data at any time for trend analysis or fault diagnosis, and supports wireless transmission and various flexible data transmission methods to meet the needs of different users and application scenarios.

[0032] The data acquisition module also includes a temperature compensation method to correct the measurement results of the electronic sensor, taking into account the impact of ambient temperature changes on the electronic sensor output. Specifically: An ambient temperature sensor is installed inside the bimetallic thermometer to monitor the temperature of the surrounding environment in real time. The output signal of the ambient temperature sensor will be used as reference data for temperature compensation. Under different known ambient temperatures, the bimetallic thermometer was measured multiple times, and the actual temperature of the bimetallic strip, the ambient temperature, and the output value of the electronic sensor were recorded. The multiple recorded data will be used to establish a temperature compensation model. The compensation value is calculated using a temperature compensation model, and then applied to the output signal of the electronic sensor to obtain the corrected electrical signal. The corrected electrical signal is then transmitted to the data analysis module for further processing.

[0033] The technical effects of the above solution are as follows: by monitoring the ambient temperature in real time, establishing an accurate temperature compensation model, calculating the compensation value and correcting the sensor output signal, the temperature can be measured more accurately, the influence of ambient temperature changes on the measurement results can be reduced, and the measurement accuracy and reliability of the electronic sensor can be significantly improved.

[0047] The working principle and beneficial effects of the above technical solution are as follows: By acquiring basic calibration information such as the response time, resolution, and usage status data of the measurable temperature difference bimetallic thermometer, multiple key factors affecting the thermometer's measurement performance are comprehensively considered. The response time reflects the thermometer's reaction speed to temperature changes, the resolution reflects the minimum temperature change it can measure, and the usage status data considers actual usage conditions such as the thermometer's usage time and the number of temperature cycles. Based on this information, the temperature response coefficient and temperature measurement sensitivity evaluation value are calculated, which can more accurately assess the thermometer's actual measurement performance, thereby providing a scientific basis for calibration and ensuring the accuracy of the thermometer's measurement results. When the temperature measurement sensitivity evaluation value is less than the preset temperature measurement sensitivity evaluation threshold, a calibration reminder is issued. This allows users to promptly detect a decline in the thermometer's measurement performance and perform calibration operations, avoiding a series of problems caused by inaccurate thermometer measurements. For example, in some industrial production processes with strict temperature control requirements, inaccurate temperature measurements may affect product quality; timely calibration reminders can effectively prevent such problems from occurring.

[0048] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0049] Example 1 1. Application Scenario Description In industrial production, heat exchangers are used to transfer heat from one fluid to another to achieve heating or cooling. To ensure efficient operation of a heat exchanger, accurate measurement of the temperature difference between the inlet and outlet is necessary. This example demonstrates how to use a bimetallic thermometer capable of measuring temperature difference to monitor the inlet and outlet temperature difference of a heat exchanger.

[0050] 2. Installation and configuration of the thermometer 1) Installation location: Install a temperature measuring unit (movable rod 1) at the inlet of the heat exchanger.

[0051] Install another temperature measuring unit (movable rod 2) at the outlet of the heat exchanger.

[0052] Two temperature measuring units are connected to the dial 1 via sleeve rod 2, ensuring that the length of the two temperature measuring units can be adjusted by adjusting component 5 to accommodate different installation positions.

[0053] 2) Configuration parameters: Data acquisition module: Equipped with electronic sensors to capture mechanical deformation signals of the bimetallic strip.

[0054] Data analysis module: Set preset thresholds, assuming the temperature difference threshold is 10°C-30°C, to determine whether the temperature difference is abnormal.

[0055] Results display module: Equipped with an LCD screen and a buzzer, used to display temperature difference and issue alarm reminders.

[0056] 3) Testing and Data Recording During the operation of the heat exchanger, the inlet and outlet temperatures and temperature difference, as well as alarm status, are recorded regularly. The following is a table of test data: Working principle: Through the symmetrically arranged double sleeve rod 2, movable rod 3, and internal bimetallic strip 32 structure, combined with the double scale and double pointer 4 on the dial 1, it can simultaneously measure and display the temperature values ​​of two different locations or different objects, providing users with richer temperature information and meeting the needs of comparing two temperatures simultaneously in some special situations. At the same time, with data acquisition and analysis, it can automatically calculate and display the temperature difference between two points in real time, and can monitor the temperature changes of the environment on both sides in real time, and promptly detect potential temperature anomalies. It solves the inconvenience of traditional single bimetallic thermometers that cannot directly measure temperature differences and require manual calculation and comparison of two independent instruments. In addition, through the coordinated cooperation of sleeve rod 2, movable rod 3, and adjustment component 5, the applicability and flexibility of the bimetallic thermometer are greatly improved, enabling the bimetallic thermometer to adapt to various complex measurement scenarios.
