The TGS 2616-C00 is a hydrogen detection sensor designed with high selectivity to hydrogen, making it ideal for applications where accurate hydrogen detection is critical. It features a metal oxide semiconductor (MOS) layer on an alumina substrate with an integrated heater, housed in a compact TO-5 package. The sensor operates by converting changes in conductivity to an output signal that corresponds to the concentration of detectable gases in the air. It is engineered to reduce the influence of interference gases such as alcohol, ensuring a highly selective response to hydrogen. This sensor is suitable for use in steel plant safety, portable gas detectors, leak detection for gas appliances, hydrogen leak detectors for fuel cells, and safety measures for lithium-ion batteries. The sensor requires a simple electrical circuit to convert conductivity changes into an output signal, and it is optimized for low power consumption and small size. The sensors performance is tested under standard conditions, with a typical detection range of 30 to 4000 ppm of hydrogen.

  • Converts conductivity changes into an output signal using a simple electrical circuit.
  • Typical detection range: 30–4000 ppm hydrogen.
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.
