Electronic differential pressure switches Smart DCM DIFF produced by Honeywell / FEMA are microprocessor-controlled pressure measurement devices for differential pressures of 0…20 bar. They are suitable for an extremely wide range of applications, including the precision recording, monitoring, and control of system pressures. They come complete with an angled M12x1 plug and are mounted directly to the pipe via two G1/4″ internal thread connections.
