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

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℃.

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.
