Fsm-t-04a combustible gas sensor module description
The fsm-t-04a combustible gas sensor module is a new unit which utilizes tgs6812, catalytic pellistor type gas sensor which features durability and stability. This module provides analog output voltage proportional to hydrogen gas concentration.(there is a memory in module, where factory calibration data has been store). Fsm-t-04a has conformal coatings for moisture proofing and electrical insulation purposes, and is also capable of detecting sensor wire breakage. The unit has a wide range of operating temperature from -10 to +70'c.

Furthermore, the unit can detect ch4, lpg, h2. It is less sensitivity to vocs gas, it immunes poison by silicon compounds, it suits to work at rugged environment.

Fsm-t-04a combustible gas sensor module features:
* linear analog output proportional to gas concentration
* maintenance free
* compact size
* meets rohs requirements

Fsm-t-04a combustible gas sensor module applications:
* gas leak detection in fuel cell systems
* hydrogen & combustible gas leak detectors
