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