Has the advantages of a pressure switch but works like a Pressure Transducer with mA output. The value of mA output will change when the contact of the switch opens or closes. The value of the mA output is determined by the supply voltage and the resistors selected.

  • Up to 1,000 x Overpressure
  • No EMI issue
  • Recognizes line break
  • Recognizes short-circuit
  • No external excitation required
  • Field or factory adjustable

A wide-range of plug-in types, supplementary functions, seal materials, and accessories are available.
