Gas Detector Working Principle
A gas detector is a special gas safety concentration detection instrument, equipped with various types of gas sensors, such as electrochemical sensors, infrared sensors, semiconductor sensors and so on. Its working principle is to detect the gas concentration in the environment through the sensor, and the detection result is converted into an electrical signal, and then processed and analyzed, and finally shows the gas concentration or alarm signal. The core of the gas detector is the sensor, which according to the different detection gases, the working principle of the distinction is not the same. Common working principles of gas detectors include catalytic combustion, electrochemical, infrared, PID, semiconductor and other principles.
