D21 PRESSURE TRANSMITTER

The model D21 Pressure Transmitter is suitable for measuring pressures from -1 to 1000bar with maximum working pressures up to 1200bar.

The D21 SMART Pressure Transmitters are suitable for measurement of pressure, underpressure, and absolute 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 specifically selected type of manometric liquid. The casing is made of cast aluminium alloy or 316 stainless steel with degree of protection IP66/67. The design of the casing enables the use of a local display, rotation of the display by 90° 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 D21 SMART Pressure Transmitters are suitable for use in a wide range of applications. 

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 opposite to illuminate the display!)

The D-Series can also be supplied with Delta’s 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 Delta’s USB/Bluetooth to HART converter.

D-Soft features include:

• Identification of individual transmitter
• Configuration of output parameters
• Readings of currently measures values
• Enforcement of output current with a given value
• Transmitter calibration
• Zeroing
