These ‘smart’ pressure transmitters provide high accuracy pressure measurement incorporating 2 wire microprocessor based technology and are suitable for measuring gauge pressure, vacuum and absolute pressure of gases, vapours and liquids. 

Local configuration can be carried out in the field via the pushbuttons inside the housing or from a remote point via the 2 wire 4 - 20 mA line and communication via the HART® protocol. 

The measured pressure is indicated on the integral LCD display in selectable units and a 4 - 20 mA output signal generated, directly or inversely proportional to the connected pressure. 

The LCD display can be rotated within the housing to ensure the measured readout can be easily viewed regardless of the angle of installation. The active sensing element is a piezoresistant silicon sensor separated from the process medium by a metal diaphragm and a manometric fluid to provide highly accurate measurements.

Thermal drift is automatically compensated via a thermister integrated into the pressure sensor and this coupled with the high accuracy sensor ensures a precison measuring system which will satisfy the most demanding applications. 

The transmitters are suitable for hazardous or nonhazardous areas, the former being certified either ATEX/IECEx Flameproof (Exd) or Intrinsically Safe (Exia). All ranges available with SIL 2 certification.
