PRESSURE TRANSMITTERS
D21 Smart HART Pressure Transmitter – D-Series

Aluminium or stainless steel enclosure – all industry applications
The D-Series pressure transmitters offer customers reliable and accurate solutions to their individual process requirements. This product has a wide range of process connections and is easily configurable via the D-Soft software. The D-Series can be used for a variety of applications when pressure, differential pressure, temperature, level or flow measurements are needed. The D21 Pressure Transmitter is suitable for measuring pressures from -1 to 1000bar with maximum working pressures up to 1200bar. It is intrinsically safe and flameproof, and ATEX and IECEx rated, giving users confidence in aggressive environments.
Differential Pressure Transmitter D31 – D-Series

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 a IP66/IP67 rating. 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.
387 Analogue Pressure Transmitter

Designed for heavy duty applications
The Delta Mobrey 387 pressure transmitter has a compact, robust, all stainless steel construction making it particularly suited to the harsh corrosive environments of offshore applications. It also offers excellent accuracy of 0.15% of the upper range value, including combined effects of linearity, hysteresis and repeatability,
