Pressure Gauge Calibration using a Dead Weight Calibrator - Armfield F1-11

Описание к видео Pressure Gauge Calibration using a Dead Weight Calibrator - Armfield F1-11

Dead weight calibration is a primary standard method used to calibrate pressure gauges. In this method, a known mass is applied to a piston that rests on a measuring surface and the resulting pressure is measured by the pressure gauge being calibrated. The pressure is calculated by dividing the mass applied to the piston by the effective area of the piston. The process is repeated with increasing weights until the full range of the pressure gauge is covered.

The main advantage of the dead weight calibration method is that it provides a highly accurate and traceable calibration, as the mass used for calibration is traceable to the International System of Units (SI). The method is suitable for calibrating a wide range of pressure gauges, including low-pressure and high-pressure gauges, with high accuracy and repeatability.

In practice, dead weight calibration requires specialized equipment, including a dead weight tester, a piston and cylinder, and weights with traceable mass. The process is usually carried out in a controlled environment to minimize the effects of temperature and other variables that can affect the accuracy of the calibration.
