XENSIV™ TCI H2 gas sensor – a hydrogen sensor based on the thermal conductivity principle

The XENSIV™ TCI H2 gas sensor reliably detects hydrogen (H2) in demanding automotive and industrial applications like FCEVs, hydrogen combustion engines, refueling stations, BEVs, ESS, electrolyzers, and stationary fuel cells. It operates on the thermal conductivity (TC) principle, using a differential MEMS design to measure heat transfer through gas. Unlike chemical-based sensors (e.g., MOX, CC), it is resistant to poisoning and offset drift, ensuring high robustness and stability.
