Differential pressure transmitter TRDU

Gram pressure transmitter is excellent as signaller for frequency converters (with PID-regulation). Available in two types for pressure ranges from 0 to 50 kPa.
Differential pressure transmitters are ideal for reference signal for units with constant vacuum. Both types have a compact design and are equipped with screw holes for wall mounting. Are delivered incl. connection piece and 2m sensor hose.

Product Features

  • Quick and easy mounting
  • Supply: 10-35 VDC (2-cable supply)
  • Favorable price
  • Advantageous performance ratio

Further data

  • Gram pressure transmitters are especially suitable as signaller for frequency converters (with PID-regulation).
  • Emits a signal signal 4-20mA, dependant on sensing of actual vacuum on the ventilation system.
