A mis-calibrated pressure switch can miss a trip point, allowing overpressure events that damage equipment and endanger personnel. This guide covers the complete workshop calibration procedure for pressure switches, from isolation through deadband verification, using the rising-falling test method with Honeywell pressure switches and Yokogawa loop-powered indicators.
