Product Description

The XMD process DP cell is designed for use in control and monitoring applications on process sites such as oil refineries, pharmaceutical plant, chemical manufacture, power stations, food processing and paper mills.

HART communications is enable as standard allowing the operator to access device information such as type, range and serial number and carry out re-ranging or re-calibration procedures via a HART compatible programming handset.

For convenient stocking of spares and rapid configuration across a number of different applications the 4-20mA output of the transmitter can be rescaled down to 1/10 of the nominal pressure range.  A 0.1% of full scale is manitained down to 1/5 of the range beyond which the accuracy will gradually decrease to a maximum of 0.25% at 1/10 of the nominal range.

The XMD HART pressure transmitter is adaptabe to many different purposes on a process site. The output can be switched to a square root extraction for use as a flow measurement device. The negative port can be left vented to create a gauge reference process transmitter, it can installed with an IS barrier for use in a area where an explosion caused by gas or dust is a potential hazard.  By fitting oil filled diaphragm seals the XMD DP transmitter can be modified for use with paper pulp, high temperature steam, food or drink.  By extending the seals with capillaries the process transmitter can be converted to liquid level tranmsitter for measuring the height of liquid contents in a sealed tank.
