Description

Technical Field

[0001] This application relates to the field of sensor technology, and specifically discloses a corrosion-resistant sensor. Background Technology

[0002] A gas sensor is a device that converts information such as the composition and concentration of a gas into information that can be used by personnel, instruments, and computers. Gas sensors are suitable for monitoring almost all volatile gases. Gas sensors have significant advantages such as high accuracy, good selectivity, high reliability, non-poisoning, oxygen independence, minimal susceptibility to environmental interference, and long lifespan.

[0003] In industrial production, gas sensors are typically installed on the walls of production sites to monitor the air in the environment and prevent gas leaks that could cause accidents. Real-time monitoring is especially crucial for hazardous chemical gases. However, gas sensors used in industry are susceptible to corrosion due to prolonged contact with chemical gases, which can shorten their lifespan. Therefore, the inventors have developed a corrosion-resistant sensor to address this problem. Utility Model Content

[0004] The purpose of this invention is to solve the problem that traditional gas sensors are easily corroded by chemical gases in the environment, which affects their service life.

[0005] To achieve the above objectives, the basic solution of this utility model provides a corrosion-resistant sensor, including a sensor body and a controller. One end of the sensor body has an inlet pipe, and the bottom end has an outlet pipe. A gas concentration detection probe for detecting the gas input into the inlet pipe is installed inside the sensor body. A data processing module for processing the detection data and transmitting it to the controller is also installed inside the sensor body. The gas concentration detection probe is vertically mounted inside the sensor body, located between the inner end of the inlet pipe and the outlet pipe. An alarm is also installed on the outer side of the sensor body. Both the gas concentration detection probe and the alarm are electrically connected to the controller. The inner walls of the inlet and outlet pipes are coated with a first inert coating, and the outer surfaces of the sensor body, inlet pipe, outlet pipe, and alarm are coated with a second inert coating. The sensor body can be detachably installed on the wall of the industrial production site.

[0006] The principle and effect of this basic scheme are as follows:

[0007] 1. Compared with existing technologies, this utility model facilitates the detection of gas concentration in industrial production sites by setting up an inlet pipe, an exhaust pipe, and a gas concentration detection probe. The vertical installation of the outlet pipe and the inlet pipe at one end of the sensor body facilitate the introduction of gas into the sensor body. The first inert coating provides corrosion protection for the inner walls of the inlet and outlet pipes, which are in long-term direct contact with the detected gas. The second inert coating provides corrosion protection for the outer surface of the overall structure. Through internal and external corrosion protection, the corrosion resistance of the sensor structure is improved, preventing chemical gases from corroding its structure and thus maintaining the service life of the gas sensor. This solves the problem that traditional gas sensors are easily corroded by chemical gases in the environment, affecting their service life.

[0008] Furthermore, the first inert coating is an inert inorganic copolymer coating. By using an inert inorganic copolymer coating, it is easier for it to adhere more closely to the pipe walls of the inlet and outlet pipes, resulting in better corrosion protection.

[0009] Furthermore, the second inert coating is a zinc-plated coating. By using a zinc-plated coating for corrosion protection on the surface of the sensor body, it is easier for the second inert coating to integrate with the structure of the sensor body.

[0010] Furthermore, the sensor body is provided with several limiting blocks evenly distributed around its periphery, each of which has a threaded through hole. The sensor body is then connected and installed to the wall of the industrial production site using threaded fasteners. The limiting blocks and threaded through holes facilitate the structural installation and fixation of the sensor body.

[0011] Furthermore, the sensor body has an internally threaded connecting tube at its end, and the alarm has an externally threaded connecting tube at its bottom that is detachably threaded to the internally threaded connecting tube. The alarm and sensor body are mounted and fixed together via the externally and internally threaded connecting tubes, resulting in a more compact structure and easier use and portability.

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0015] The reference numerals in the accompanying drawings include: sensor body 1, air inlet pipe 2, air outlet pipe 3, gas concentration detection probe 4, data processing module 5, alarm 6, first inert coating 7, second inert coating 8, limit block 9, threaded through hole 10, internal threaded connecting pipe 11, and external threaded connecting pipe 12.

[0016] A corrosion-resistant sensor, implemented as follows: Figure 1 As shown: It includes a sensor body 1 and a controller, the controller including but not limited to a single-chip microcomputer controller. The left end of the sensor body 1 is provided with an air inlet pipe 2 and the bottom end of the sensor body 1 is provided with an air outlet pipe 3. A gas concentration detection probe 4 for detecting the gas input into the air inlet pipe 2 is installed inside the sensor body 1. A data processing module 5 for processing the detection data and transmitting it to the controller is also installed inside the sensor body 1. The gas concentration detection probe 4 is vertically installed inside the sensor body 1 and is located between the inner end of the air inlet pipe 2 and the air outlet pipe 3. An alarm 6 is also installed on the outside of the sensor body 1. Both the gas concentration detection probe 4 and the alarm 6 are electrically connected to the controller. The inner walls of the air inlet pipe 2 and the air outlet pipe 3 are provided with a first inert coating 7. The outer surfaces of the sensor body 1, the air inlet pipe 2, the air outlet pipe 3 and the alarm 6 are provided with a second inert coating 8. The sensor body 1 can be detachably installed on the wall of the industrial production site.

[0017] Among them, such as Figure 1 As shown, the first inert coating 7 is an inert inorganic copolymer coating. The second inert coating 8 is a zinc plating coating.

[0018] Among them, such as Figure 1 As shown, three limiting blocks 9 are evenly arranged on the periphery of the sensor body 1. Each limiting block 9 is provided with a threaded through hole 10. The sensor body 1 is connected and installed to the wall of the industrial production site using threaded fasteners, including but not limited to screws.

[0019] Among them, such as Figure 1 As shown, the sensor body 1 has an internally threaded connecting pipe 11 at its end, and the alarm 6 has an externally threaded connecting pipe 12 at its bottom that is detachably connected to the internally threaded connecting pipe 11.

[0020] In the specific implementation of this utility model, three screws are used to engage with the threaded through holes 10 on the three limiting blocks 9, thereby fixing the sensor body 1 to the wall surface of the industrial production site. The gas in the industrial production site enters the sensor body 1 through the air inlet pipe 2, and the gas concentration detection probe 4 installed in the sensor body 1 detects the incoming gas. The data processing module 5 processes and transmits the detection data, and transmits the detection results to the controller in a timely manner. When the gas data displayed in the detection results does not conform to the industry standards, the controller controls the alarm 6 to issue an alarm response. When the gas data displayed in the detection results conforms to the industry standards, the detection continues.

[0021] Compared with existing technologies, this utility model facilitates the detection of gas concentration in industrial production sites by setting up an inlet pipe 2, an extraction pipe, and a gas concentration detection probe 4. By setting up a first inert coating 7, it facilitates corrosion protection of the inner walls of the inlet pipe 2 and the outlet pipe 3, which are in long-term direct contact with the detected gas. By setting up a second inert coating 8, it facilitates corrosion protection of the outer surface of the overall structure. Thus, through internal and external corrosion protection, the corrosion resistance of the sensor structure is improved, and chemical gases are prevented from corroding the structure, thereby maintaining the service life of the gas sensor structure and solving the problem that traditional gas sensors are easily corroded by chemical gases in the environment, affecting their service life.
