Description

Technical Field

[0001] The utility model relates to the technical field of conductivity sensors, in particular to an electrode type conductivity sensor. Background Art

[0002] Electrode-type conductivity sensors are important measuring devices widely used in the power, chemical, environmental, food, semiconductor, and marine research and development industries to measure the electrical conductivity of liquids. Based on the principle of electrolytic conductivity, electrode-type conductivity sensors employ a resistance measurement method to measure the conductivity of liquids. During the measurement process, the conductivity measuring electrode behaves as a complex electrochemical system. By applying a constant voltage to the electrode and monitoring the current changes caused by changes in the liquid's resistance, the liquid's conductivity is calculated.

[0003] In practical applications, the interfaces of electrode-type conductivity sensors do suffer from wear and damage due to long-term use and frequent plugging and unplugging, which can lead to them easily falling off during connection. The root cause of this problem is mechanical wear and aging of the interface components.

[0004] Specifically, the interface design of electrode-type conductivity sensors typically includes connectors such as pins and sockets. These components wear out over time due to frequent plugging and unplugging. When wear reaches a certain level, the fit between the interface components degrades, and the sensor may even become loose. When the interface becomes loose enough, the sensor may fall during connection, affecting measurement stability and accuracy while also posing a potential safety hazard to both equipment and personnel.

[0005] Furthermore, if impurities or corrosion are present at the interface, this will exacerbate the wear process and further shorten the service life of the interface components. Therefore, in practical applications, it is necessary to regularly inspect and maintain the interface of electrode-type conductivity sensors to promptly detect and address wear and looseness issues to ensure the normal operation of the sensor and measurement accuracy.

[0026] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0027] When exploring an electrode-type conductivity sensor, we must meticulously describe each component and its ingenious design. With its superior performance and easy operation, this sensor plays an irreplaceable role in numerous industrial and scientific research fields. The sensor's overall structure is composed of a stable and sturdy sensor housing 1, providing a solid protective shell for the delicate components within.

[0028] See also Figure 1 - Figure 4 As shown, the sensor connector 2, which serves as a bridge connecting the sensor to external equipment, is cleverly located at the lower end of the sensor housing 1. This design not only facilitates installation and removal but also ensures the stability of the sensor in various operating environments. A key design feature is the docking port 3 at the lower end of the connector, featuring a built-in connecting thread 6. This detail ensures a fast and reliable connection. Inside the docking port 3, a connecting sleeve 8 achieves a seamless connection through a matching thread 9 that perfectly matches the connecting thread 6, enhancing the sensor's sealing and durability.

[0029] The design of the connector sleeve 8 is equally ingenious. Its two sets of docking slots 10 not only meet different interface requirements but also enhance the overall compactness of the structure through clever layout. The top set of docking slots 10 precisely aligns with the through-slot 5, ensuring unimpeded signal transmission. The inner fixing frame 11, connected within the bottom set of docking slots 10, doubles the stability of the connector pins 4 with outer retaining plates 12. This design effectively prevents measurement errors caused by poor contact or looseness.

[0030] The design of the through-slots 5 is equally unique. They are distributed in a circular pattern on the sensor connector 2, adopting a square groove design with cleverly curved inner corners. This detail not only enhances the durability of the through-slots 5 but also reduces fluid resistance, improving the sensor's measurement accuracy. Furthermore, the ingenious combination of the connecting thread 6 and the adapting thread 9 makes installation and removal of the connecting sleeve 8 exceptionally simple, enhancing work efficiency.

[0031] As an extension of the connecting sleeve 8, the bottom ring 7 not only enhances the overall aesthetics but also provides a comfortable grip thanks to its non-slip texture. The sealing ring bonded to the top of the bottom ring 7 further enhances the sensor's sealing performance, ensuring the accuracy of measurement results.

[0032] The material selection for the inner retaining frame 11 and outer retaining plate 12 is also commendable. They are punched from elastic sheet metal, ensuring both sufficient strength and a certain degree of elasticity. The "C"-shaped cross-section of the outer retaining plate 12 cleverly utilizes the material's elastic properties to securely secure the connector pins 4. The gap between the two outer retaining plates 12 effectively prevents deformation caused by material expansion, ensuring the stability of the sensor during long-term use.

[0033] In summary, this electrode-based conductivity sensor, through its sophisticated structural design and high-quality material selection, achieves a perfect combination of high precision, high stability, and easy operation. It not only plays an important role in industrial automation control and water quality monitoring, but also provides reliable experimental data support for scientific research. With the continuous advancement of technology and the continuous expansion of its application fields, it is believed that this sensor will play an even more important role in the future.

[0034] The installation process is as follows: Place the sensor housing 1 on a stable work surface, ensuring that no debris can interfere with the installation process. Next, align the sensor connector 2 with the lower end of the sensor housing 1 and gently screw it in, ensuring that the sensor connector 2 is firmly fixed to the sensor housing 1. Then, with the docking port 3 facing downward, connect the threaded connection 6 to the corresponding port on the external device. Ensure that the threaded connection 6 closely matches the threads of the external device and tighten appropriately to ensure a secure connection.

[0035] During the connection process, align the adapting threaded portion 9 of the connecting sleeve 8 with the connecting threaded portion 6 of the docking interface 3, and rotate the connecting sleeve 8 clockwise until the adapting threaded portion 9 is fully engaged with the connecting threaded portion 6. At this point, the connecting sleeve 8 is firmly mounted on the sensor connector 2. Next, select a suitable docking slot 10 for connection according to actual needs. Insert the interface of the external device into the corresponding docking slot 10 and ensure that it is firmly fixed on the connecting sleeve 8. After the top set of docking slots 10 are precisely aligned with the through slots 5, the signal transmission channel is established. At this point, check whether the signal transmission is unobstructed to ensure that the sensor can receive and transmit data normally. For the inner fixing frame 11 and the outer tightening plate 12 in the bottom set of docking slots 10, they will doubly stabilize the connector pin 4. After confirming that the pin has been correctly inserted into the docking slot 10, gently press the outer tightening plate 12 so that it fits tightly around the pin to achieve a firm fixation.

[0036] During installation, pay attention to the non-slip texture of the bottom ring 7 to ensure a comfortable and stable grip during installation and removal. Also, check that the sealing ring on the top of the bottom ring 7 is intact to ensure the sensor's sealing performance. Finally, check that the entire installation process complies with specifications, ensuring that all components are correctly installed and securely fastened. Then, perform a preliminary test of the sensor to verify that its performance meets requirements. This completes the installation process for the electrode-type conductivity sensor.
