Pressure measurement in hazardous areas
17 October 2008
The Gefran XPSA pressure transmitter features a bonded strain gauge measurement technique to produce a rugged, compact sensor with a stainless steel diaphragm. The high accuracy, high stability (0.1% of FS) and fast response (<1msec) unit is insensitive to vibration and benefits from intrinsically safe hazardous area approvals (ATEX EEXia IIC T4/T6).
The standard ranges are 0 – 50 bar, up to as high as 0 – 1,000 bar, with most standard process connections available, such as G1/4, G1/2, 7-16UNF and 1/4NPT.
The XPSA offers a standard 4-20mA output proportional to pressure, on a supply from 10V to 30V dc, and is available with a moulded cable or several standard styles of electrical connector, protected to IP65 and IP67.
