Japan figaro Freon sensor for detecting refrigerant gas - TGS2630

1. Description of Japan Figaro Freon sensor TGS2630:

The sensing element consists of an integrated heater and a tin oxide (SnO2) semiconductor on an alumina substrate. When the gas to be detected is present in the air, the higher the concentration of the gas, the higher the conductivity of the sensor. Using a simple circuit, the change in conductivity can be converted into a signal output corresponding to the gas concentration.

Freon sensorTGS2630 is widely used to detect refrigerants R-404a and R-410a commonly used in air conditioners and refrigeration equipment, and also has high sensitivity to non-flammable refrigerant gases R-32 and R-1234yf that help prevent global warming. Due to the built-in filter layer, its sensitivity to volatile alcohols (common interfering gases in living environments) is very low, demonstrating high selectivity for non-flammable refrigerants. Since the sensing element is very small, the heater current of TGS2630 is only 56mA, and the housing adopts a standard TO-5 metal package.
