Electronic Pressure Switches

Electronic pressure switches offer a multitude of advantages in comparison with mechanical pressure switches and contact manometers. They convince though greater accuracy, freedom from wear, long-term stability, simpler operation and the high number of switching cycles, among other things.

Type series

without measurement value display  
  • EDS 4000, for mobile and stationary hydraulics, set ex-works or programmable,
    depending on the version for explosion-hazard environments with ATEX, CSA, IECEx approval
  • EDS 810 for OEM applications in the the industrial and mobile sectors, factory preset,
    with ECE type approval for public road traffic, optionally with IO-Link interface
  • EDS 710, for series applications in industrial and mobile sector where the dimensions of the cavity are tight, extremely small, compact design, set ex-works
  • EDS 410, for OEM applications, factory preset or programmable
