An Investigation on the Techniques used in Force Calibration using Deadweights and Pressure Piston Gauge

Mahmoud, Gouda M; Gelany, Shaker A; Aggag, Gamal A


This paper presents two mechanisms for load cell calibrations. The first technique was to use deadweight to generate the required reference load (Applied load). The second method was to use a pressure piston gauge to generate the required calibration force. In both mechanisms, the setup and procedures are described. For verification the results of these methods were compared with international metrology institute calibration results. It was found that deadweight method is the most accurate and the piston gauge is the most realistic at high force values.
