» Differential Pressure Transmitter

Differential pressure sensors and transmitters measure the difference in pressure from one side to another on a diapgram or two diaphragms and defer a difference between the two measurements, common applications include measuring the pressure drop across a filter due to blockage or build up another includes measuring flow or level ia a pressurised vessel.  More details on applications can be found here.

DMD 341 Low range differential pressure transmitter

The DMD 341 is a low range differential pressure transmitter with a pressure range from 6mbar through to 1000mbar.  This pressure range can be in vacuum as well as positive pressures so +/-3mbar up to +/-500mbar is possible.  Current and Voltage output as standard and a choice of electrical connections.
