Why drift in pressure sensors can cause catastrophic plant overpressurization. Learn how deadweight testers maintain safety loops.
Pressure gauges and transmitters act as the first line of defense in chemical loop plants. Over time, physical stress causes pressure sensors to drift. Consistent calibration using hydraulic deadweight testers verifies accuracy at key operating points, satisfying Saudi Aramco GI safety mandates.
