TCI XENSIV™ TCI H2 sensor: Hydrogen sensor based on thermal conductivity principle
Infineon’s XENSIV™ TCI sensors provide reliable detection of hydrogen (H2) gas in demanding automotive and industrial applications such as FCEVs, H2 combustion engines, H2 refueling stations, BEVs (Battery Electric Vehicles), ESS (Energy Storage Systems), H2 electrolyzers and stationary fuel cells. Infineon’s XENSIV™ TCIx gas sensors operate on the principle of TC and utilize a full differential MEMS sensor concept. The TC is measured by heating up parts of the MEMS structures and measuring the heat transfer through the gas. TC sensing provides the highest robustness and stability for rough automotive applications. Unlike metal oxide based (MOX) sensors and catalytic combustion (CC) sensors, no chemical reaction takes place in TC gas sensors as they are based on a physical measuring principle. This makes TC gas sensors immune to the risk of poisoning and the tendency to high offset drift shown by chemical sensors.
