Product Description

The XMD has a standard process configuration with kidney flange mounting arrangement and large accessible electronic housing.

Other features include ATEX intrinsic safety or flameproof, linear or square root extraction 4-20mA output, HART communications, 10 to 1 turndown ranging, LCD readout and 130 bar overpressure protection on one side.

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 maintained 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 adaptable 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 be installed with an IS barrier for use in a area where an explosion caused by gas or dust is a potential hazard.
