HOW THE PRODUCT WORKS
MEMS thermal conductivity measurement for hydrogen monitoring
The TCM101 Thermal Conductivity Hydrogen Purity Sensor is independently designed and developed by the manufacturer. It uses a MEMS-based micro thermal conductivity sensor to measure hydrogen concentration from the thermal conductivity relationship of binary gas mixtures. The diffusion-sampling sensor is intended for hydrogen monitoring in hydrogen generators, hydrogen refueling stations, compressors, energy storage systems and industrial production environments.
The product reference lists two measuring ranges, 0.2–4% Vol and 0.2–10% Vol, with selectable 12 VDC or 24 VDC supply. For a suitable configuration, specify whether your target is hydrogen leak concentration or a purity-related measurement, and share the gas composition, required range and operating conditions with our team. This helps assess a thermal conductivity hydrogen purity sensor for the intended gas mixture and operating environment.
