Digital pressure switch for use with single-line lubrication systems


This electronic pressure switch has a 4-digit, digital display, two switching outputs and an analog output signal for switching point and hysteresis. Both can be adjusted via push buttons. The waterproofed housing is pivotable up to 290° for optimal readability of digital display. The pressure switch is virtually maintenance free.

Features and benefits:

  • Menu-guided adjustments via 3 push buttons indicating status of outputs
  • Peak value storage
  • Adjustable hysteresis and absorption
  • Programmable parameters
  • Password protected
  • Reverse polarity and overvoltage protected; short-circuit proof
