FCS494 - Differential pressure purge transmitter - 1

Furness Controls Differential Pressure Purge Transmitter Accuracy 0.25% of reading Ultra low pressure measurement 2-wire mA, 3-wire or 4-wire voltage output IP 65 Aluminium enclosure Purge pressure up to 2 Bar Furness Controls’ Differential Pressure Purge Transmitters overcome the long standing problem of blocked impulse lines. The units are for use with Pitot tubes, flow grids or static pressures and ensure that the holes & impulse lines do not become blocked during use where there is debris or particles in the flow. The purge units consist of a well proven differential pressure transmitter with additional software and electrically operated valves. At a timed intervals the output of the transmitter and the local display are held whilst the impulse lines are reverse purged to clear them of any potential blockage of the holes and as an added bonus during this time the transmitter is equalized and automatically zero adjusted. The units offer high accuracy of 0.25% of reading plus the option of square root extraction and two stag
