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'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 Specification: Product name: Combustible gas sensor module Model No.: FSM-T-04A Gas sensor: TGS6812 (catalytic type) Detection range: 0 ~ 50,000ppm CH4 (also can detect methane, iso-butane, and propane) Error: ±3%LEL
