Product Specification
Features:
* Linear output
* Long life
* Small sensitivity to alcohol
* Sensitive to hydrogen, methane, and LP gas
Applications:
* Hydrogen and combustible gas leak detectors for fuel cells
The TGS6812-D00 catalytic type gas sensor can detect levels of hydrogen
up to 100%LEL. This sensor features high accuracy, good durability and
stability, quick response, and linear output. This sensor can detect not only
hydrogen, but also methane and LP gas, thus making it an excellent solution
for monitoring gas leakage from staionary fuel cell systems which transform
combustible gases into hydrogen.
As the sensor possesses an adsorbent inside its sensor cap, its cross sensitivity
to organic vapors is small. In addition, TGS6812-D00 is durable against silicone
compounds in harsh environments.
The figure below represents typical sensitivity characteristics,
