H2-Hydrogen-Sensor for the definition of the nitriding atmosphere (nitriding sensor)

H2-Hydrogen Sensor for the definition of the nitriding atmosphere


Simple connection to existing automation devices (e.g. recorder, programmer, etc.) via 4-20mA output.

Measuring principle: Heat conductivity of measuring gas in nitrogen, ammonia, hydrogen and carbonic gases.

■ Applicable for nitriding, nitrocarburizing, oxy-nitriding, X-nitriding as well as carburizing processes.
■ Simple installation by convection pipe connection, which is located within the gas atmosphere.
■ Calibration gas connection and electric connection over connector.
■ No exhaust gas  over sensor.
■ The sensor works according to the diffusion principle.
■ The sensor can be connected directly to the 4-20mA input of the automation device (e.g. recorder, programmer etc.)
