Precont® DD121G

The Precont® DD121G is a universal transmitter for small differential pressures (<100 mbar).

The current differential is 3 ½-digit digital display. The device has two thresholds for monitoring and control purposes, eg for Ap-dependent cleaning in industrial dust extraction. An additional alarm threshold is used for monitoring a maximum differential pressure.

The status of the relay is indicated by LEDs. The device is dust-proof and approved for use in Ex-zone 22.
