Description
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.
