Differential Pressure Transmitter 982R from 0 to 1000 mbar.

The differential pressure transmitters of the 982R series are used to measure differential pressure, overpressure and vacuum. They provide one adjustable pressure range and one output signal. Monitoring of gaseous, non-combustible and non-aggressive media. The end of the pressure range can be reduced to 50% of its factory set full scale value simply by the use of a push-button.
