Accurate Pressure Transmitters for Measurement on Natural Gas Compressors



Telford UK - The Gefran XPSA pressure transmitters use a bonded strain gauge measurement technique, developed by Gefran to produce a rugged, compact sensor with a stainless steel diaphragm. The XPSA series offers a high accuracy and stability (0.1 % of FS) and fast response (<1 msec) unit, that is insensitive to vibration. With intrinsically safe hazardous area approvals, the Gefran XPSA is particularly suited to the monitoring of natural gas pressure in distribution plants, compressor units and pressure reduction stations, as well as for general use on chemical plants. The standard ranges available cover from 0 - 50 bar, up to as high as 0 - 1000 bar, with most standard process connections available, such as G1/4, G1/2, 7-16UNF and 1/4NPT.


The XPSA offers a standard 4-20 mA output proportional to pressure, on a supply from 10V to 30 V DC, and is available with a moulded cable or several standard styles of electrical connector, offering IP65 to IP67 ratings. The sensor diaphragm and wetted materials are 17-4 pH stainless steel (AISI 304), making the sensor suitable for most process conditions. The ATEX intrinsically safe approval is EEXia IIC T4/T6, depending on the operating temperature of the sensor, which can cover the extremes of -40C to +80C.
