D31 SMART Differential Pressure Transmitter is 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.
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.
ATEX certified for use in Zone 0/20 and Zone 1/21 Hazardous Areas and available with 316L, Hastelloy C 276 or Gold wetted parts materials, the D31 SMART Differential Pressure Transmitters are suitable for use in a wide range of applications whether for measuring differential pressure, level or flow.
When fitted with a direct diaphragm seal on the Hi side of the transmitter, the model D31 can be used for measuring level in open tanks.
One unique feature of all models in the D-Series is the backlit LCD display which facilitates local monitoring in light deficient environments by enhancing display visibility (move your mouse cursor over the image below to illuminate display).
The D-Series can also be supplied with our user-friendly ‘D-Soft’ remote communication software.
Using the HART communication protocol, this software provides users with a convenient way to calibrate, configure and monitor the instrument by connecting it to a PC via our USB/Bluetooth to HART converter.
