DIFFERENTIAL PRESSURE TRANSMITTER

The D31 SMART Differential Pressure Transmitters are suitable for measuring differential pressure of gases, vapours and liquids. The active sensing element is a piezoresistive silicon sensor separated from the medium by a diaphragm and by a specially selected type of manometric liquid.  The special design of the active sensing element ensures that it is able to withstand pressure surges and overloads of up to 250/320/413 bar. The casing is made of cast aluminium alloy or 316 stainless steel with degree of protection IP66/IP67. The design of the casing enables the use of a local display, rotation of the display by 90°, rotation of the casing by 0–355° relative to the sensor, and a choice of cable direction.

The D31 Differential Pressure Transmitter is suitable for measuring pressures from -100mbar to 70bar with maximum working pressures up to 413 bar.

Key Features
