Calibration Devices for Pressure Instrument Calibration

Calibration devices generate accurate, traceable reference values so that pressure sensors, transmitters and gauges can be verified against a known standard. In a quality system the reference itself has to be traceable, which is why the choice of calibration hardware matters as much as the instrument under test.

Two routes cover most requirements. A dead weight tester defines pressure physically – a known mass acts on a known piston area – and therefore works as a primary standard without needing a reference sensor. A hand pressure pump generates pressure or vacuum manually and is read against a separate reference gauge or calibrator, which makes it the practical choice for on-site work and for testing at the point of installation.
