Relative pressure transmitter D31

differentialmembranepiezoresistive

HART Communication, aluminium or stainless steel enclosure 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 • Die cast weatherproof enclosure to IP66 (NEMA 4). • Stainless steel mechanism. • Internal tamperproof set point adjustment. • Calibrated scale.
