Honeywell FEMA Pressure Switch – DCM / DNM

DCM / DNM series is a universal, industrial grade, heavy duty pressure switch for all corrosive, non-aggressive liquids, water, gases. It can be used in general mechanical engineering, printing machine industry, as well as in pneumatics and hydraulics, including effluent treatment, alcohol industry, manufacturing plant, automobiles etc.


Pressure Switch – Honeywell DCM / DNM

universal pressure switch can be used in general mechanical engineering and the printing machine industry, as well as in pneumatics and hydraulics. Thus, it can be used in effluent treatment plant, sea water application, chemicals, hydrocarbons, petrochemicals, STP, WTP etc.
