Problems solved by technology

[0003] The pressure sensor on the natural gas pipeline is a device or device that can sense the pressure signal and convert the pressure signal into an available output electrical signal according to certain rules. When the pressure sensor is installed, it is easily affected by external pressure. A protective device needs to be installed, but the existing protective device usually installs a protective shell on the outside of the pressure sensor. This protective shell is inconvenient to install and disassemble, which increases the time of installation and disassembly, and this protective shell cannot be effective If the pressure sensor is stably fixed, it is easy to cause damage to the pressure sensor under the impact or extrusion of external pressure, shorten the service life, and increase the cost of use. For this reason, we propose an electrochemical sensor based on graphene composite materials protective devices to solve the above problems

Abstract

The invention discloses a protection device for an electrochemical sensor and based on a graphene composite material. The protection device comprises a protection box and a pressure sensor body, connectors are connected to two sides of the pressure sensor body, one ends of the connectors are connected with flanges, and natural gas conveying pipes are connected to one ends of the flanges. A protection cavity is formed in the protection box, a second opening is formed in the upper end of the protection cavity, and U-shaped openings are formed in both sides of the upper end of the protection cavity. The protection device not only solves the problem that the pressure sensor body is inconvenient to clamp stably, but also solves the problem that the pressure sensor body is inconvenient to install and disassemble stably, improves the stability of the pressure sensor body, can stably protect the pressure sensor body, avoids the condition that the detection data is influenced due to the fact that the stability of the pressure sensor body is poor when the natural gas conveying pipes are detected, and improves the efficiency of installation and disassembly.

Description

technical field [0001] The invention relates to the technical field of electrochemical sensors, in particular to a protective device for electrochemical sensors based on graphene composite materials. Background technique [0002] The earliest electrochemical sensors date back to the 1950s, when they were used for oxygen monitoring. By the mid-1980s, small electrochemical sensors were used to detect many different toxic gases in the PEL range and showed good sensitivity and selectivity. Electrochemical sensors work by reacting with the gas being measured and producing an electrical signal proportional to the gas concentration. A typical electrochemical sensor consists of a sensing electrode (or working electrode) and a counter electrode, separated by a thin electrolytic layer. At present, various electrochemical sensors are widely used in many static and mobile applications for personal safety. , especially the pressure sensor in the electrochemical sensor is widely used in...
