Preventive and Resolving Measures for Sensor Poisoning in Gas Detectors
(1) Avoid contact with toxic substances
Do not use gaskets, seals, and insulation components containing silicone rubber, synthetic rubber, or sealants; Do not use silicon-based polishing agents, cleaning agents, and lubricants in environments where instruments are assembled and stored; Avoid using lubricants containing silicides for components such as gas transmission pipeline valves; Do not use adhesives containing silicides and self-adhesive labels on the surface of the instrument; Installation and maintenance personnel should not use cosmetics containing silicone oil components.
(2) Correct installation and use
Correctly select the installation location of the gas detector and avoid exposing the sensor probe to environments with irritating substances. Choose a gas detector with an appropriate range according to the actual situation, and try to avoid the sensor working for a long time in a high concentration environment of leaked gas as much as possible. Reduce the exposure time of sensors to toxic gases in the environment, and turn off the instrument when not in use.
(3) Regular maintenance and calibration
Strictly follow the installation and maintenance guidelines of the instrument, regularly maintain and calibrate the gas detector to ensure its normal operation. After exposure to highly toxic gases, clean the sampling pump, replace the gas circuit and gasket.
In summary, gas detector sensor poisoning is often caused by contact with highly corrosive, high concentration gases, or impurity adsorption. By standardizing the usage process, conducting regular calibration and maintenance, and selecting appropriate models, the risk of poisoning can be effectively reduced, ensuring the accuracy and reliability of sensors, and building a solid safety barrier for safety production and environmental monitoring.
