Delta Mobrey D22 Pressure Transmitter


The model D22 Pressure Transmitter is suitable for measuring pressures from 0 to 25 mbar up to 0 to 1000bar with maximum overpressure up to 1200bar.

The D22 Pressure Transmitters is a low cost solution for the measurement of pressure, underpressure, and absolute pressure of gases, vapours and liquids. Available in a wide range of blind and compact construction for a wide range of industrial application.  The active sensing element is a piezoresistive silicon sensor separated from the medium by a diaphragm and by a specifically selected type of manometric liquid.

From the simple flying leads electric connection to standardized connector IP65/IP68 or even an all Stainless Steel enclosure with internal terminal board, to cover almost all the application. Threaded with rear or flush diaphragm process connection and several type of chemical seal are available, to measure any type of process fluid and condition.
