Tips: Working Principle of Gas Detector Sensors

1. Electrochemical Sensors
Due to the active chemical properties, the testing gases generally have reducibility or oxidizability. Electrons are released or absorbed in the chemical reactions and a large number of electrons form a current. The current is proportional to the gas concentration, thus the gas concentration is obtained by measuring the current.

2. Catalytic Combustion Sensors
It works based on the principle that the heat is released from the combustion reaction of a surface combustible gas, namely combustion increases the temperature of the platinum wire coil and thus the resistance of the coil increases. The gas concentration is obtained by measuring the resistance value change of platinum wire. It’s suitable for measuring low concentration combustible gas.

3. PID Photo Ion Sensors
High energy ultraviolet rays ionize the organic gases, and then amplify the current of charged ions on the plate to measure. The current value reflects the gas concentration.

4. Infrared Sensors
Different combustible gas has different absorption ability to infrared ray. The concentration of combustible gas can be measured by detecting the current on the infrared photosensitive component.

5. Semiconductor Sensor
Due to the absorbability of semiconducting materials on gas, change the resistance value of the gas sensitive resistance to judge the existence of gas.
