Digital pressure switch for use with single-line lubrication systems


This compact, virtually maintenance-free electronic pressure switch has a 3-digit, digital display, one switching output and an analog output signal for switching point and hysteresis. Both can be adjusted via push buttons. For optimum adaptation to a particular application, the instrument has many additional adjustment parameters, e.g. switching delay times, NO and NC function of the outputs.

Features and benefits:

  • Integrated pressure sensor with thin-film strain gauge on stainless steel membrane
  • 3-digit, digital display
  • Compact and robust design
  • Independently adjustable switch-back hysteresis and switching point
  • Reverse polarity protection of the supply voltage, excess voltage, override and short-circuit protection are provided
  • Password protected
  • Directly installable via G 1/4 adapter into pressure line
  • Many useful additional functions
