Digital pressure switch for use with single-line lubrication systems


These virtually maintenance-free electronic pressure sensors are suitable for pressure measurements for gases and fluids. They are user friendly and can be applied easily in standard or superior applications. The space-saving housing is pivotable up to 320° for optimal readability of the 4-digit, digital display. One or two switching outputs and an analog output signal for switching point and hysteresis. Both can be adjusted via push buttons. Different value units such as bar, mbar, psi or MPa can be selected.

Features and benefits:

  • Menu-guided adjustments via 2 push buttons
  • Indication of status of outputs
  • Pre-adjustable hysteresis
  • Programmable parameters
  • Password protected
  • Reverse polarity protection of the supply voltage, excess voltage, override and short circuit protection are provided
  • Compact housing with 320 (degree symbol) pivot
  • For standard and superior applications
