The Figaro CGM6812-B00 is a combustible gas sensor module designed for applications such as gas leak detection in fuel cell systems, hydrogen and combustible gas leak detectors, and safety measures for lithium-ion batteries. It features a linear analog output voltage proportional to hydrogen gas concentration, with a detection range of 0 to 14,000 ppm H2. The module also detects methane, iso-butane, and propane.
This module incorporates Figaro's TGS6812 catalytic pellistor type gas sensor, known for its durability and stability. It includes conformal coatings for moisture-proofing and electrical insulation, and is capable of detecting sensor wire breakage. The operating temperature range is from -10°C to +60°C.
The CGM6812-B00 operates with a typical output voltage of 1-4.5V DC and requires an input voltage of 5.0 ± 0.2V DC. The output in air at standard test conditions is 1.0 ± 0.2V, and in 8000ppm H2, it is 3.0 ± 0.2V. A trouble condition is indicated by an output voltage between 0-0.1V.
This module is maintenance-free and compact, meeting RoHS requirements. It is suitable for gas leak detection in stationary fuel cells that use hydrogen generated from combustible gases.
