Description Vendor

The TGS6812-D00 is a catalytic type gas sensor can detect levels of hydrogen, methane, and LP gas up to 100%LEL. It offers linear output, long life, and minimal sensitivity to organic vapors. This sensor is ideal for monitoring gas leakage from stationary fuel cell systems, providing high accuracy, durability, and stability. It is durable against silicone compounds in harsh environments and features a proprietary filter material to reduce cross-sensitivity to organic vapors. The sensor operates by detecting changes in resistance caused by the combustion of combustible gases on its detecting element, which is part of a Wheatstone Bridge circuit. It can detect levels of hydrogen up to 100% LEL and is suitable for applications such as hydrogen and combustible gas leak detectors for fuel cells. The maximum detection range of hydrogen is 4k ppm.

Use Cases

  • Hydrogen and combustible gas leak detectors for fuel cells

Capabilities

  • Detects hydrogen, methane, and iso-butane / LP gas using a catalytic sensing element.
  • Typical detection range: 0–100% LEL of each gas.
  • Uses a Wheatstone Bridge measuring circuit to generate a change in output voltage when combustible gases are present.
  • Operating voltage: 3.0±0.1 V DC.
Figaro Engineering Inc. Figaro Engineering Inc., founded in 1968 and headquartered in Japan, became the first company in the world to develop and commercialize semiconductor gas sensors, and today offers a dedicated line of hydrogen gas sensors to enhance safety across the hydrogen economy. Figaro's hydrogen sensors (including the TGS2616 and TGS6812/FCM6812 series) are ideal for detecting hydrogen leaks in fuel cell power generation systems, hydrogen production plants, hydrogen storage and transportation facilities, and hydrogen-powered vehicles, using tin dioxide (SnO2) semiconductor sensing elements whose conductivity changes in the presence of hydrogen gas. The company's newest TGS2616 hydrogen sensor, developed with a proprietary sensing element, offers highly selective response to hydrogen with minimal interference from alcohol-based gases, addressing the safety needs of an expanding hydrogen energy market spanning fuel cell vehicles, stationary fuel cells for data centers and telecommunications, and oil and gas pipelines. Figaro's FCM6812 pre-calibrated module (built on the TGS6812 sensor) provides linear analog output proportional to gas concentration with self-diagnosis capability, and has been used for hydrogen leak detection in stationary fuel cells throughout Asia, North America, and Europe, with New Cosmos Electric Co. having acquired a partial ownership stake in Figaro in 2016.
