FES Sensor Technology Hydrogen-Sensor H2-TCD 4-20mA

H2-TCD 4-20mA is a hydrogen sensor for applications without oxygen and is based on a thermal conductivity operation principle. The sensor contains a Si-based heated transducer, fabricated by anisotropic etching, and on-board electronics, including the voltage sources for the transducer, a non-volatile digital rheostat for adjusting the Wheatstone bridge with the transducer, an instrumentation amplifier, and a secure 4-20 mA current interface. It is designed for use in a variety of applications which require an accurate hydrogen determination in nitrogen or other non-oxygen-containing atmospheres.
