Applications
     Control and regulation of industrial processes
     Monitoring of plants and switching of electric circuits
     For gaseous and liquid aggressive media that are not highly viscous or crystallising, also in aggressive ambience
     Process industry: Chemical, petrochemical, power plants,mining, on- and offshore, environmental technology, machine building and general plant construction

   Special features
    High reliability and long service life

    Up to 4 switch contacts per instrument
    Also available with liquid-filled case for high dynamic pressure loads or vibrations
    Gauges with inductive contacts for use in hazardous areas with ATEX approval
    Gauges with electronic contact for PLC applications
    Gauges in safety version S3 （k）

    Switch contacts consisting of several contacts can also be set to a single set point. Contact actuation is made when the actual value pointer travels beyond or below the desired set point.
    The pressure gauge is manufactured in accordance with DIN 16085 and fulfils all requirements of the relevant standards （EN 837-1） and regulations for the on-site display of the working pressure of pressure vessels.
    As switch contacts magnetic snap-action contacts, reed switches, inductive contacts - for requirements to ATEX - or electronic contacts for triggering a PLC are available.
    For further information on the different switch contacts please see data sheet AC 08.01.
