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

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.
