Oct 6, 2016 · A deadweight tester (DWT) is a calibration standard which uses a piston cylinder on which a load is placed to make an equilibrium with an applied pressure underneath the piston. The formula to design a DWT is based basically is expressed as follows : p = F / A [Pa] where : p : reference pressure [Pa] F : force applied on piston [N]

Apr 20, 2021 · What is a Dead Weight Tester? Dead Weight Tester (DWT) is a pressure measurement instrument that calibrates pressure based on the weight of force divided by the area the force is applied. DWT provides high accuracy in pressure gauge calibration and prevents the occurrence of an error in pressure reading.
The deadweight tester (DWT) is a very robust and flexible pressure measurement standard. This guide is intended to simplify the process of selecting the right deadweight tester for your application. The following considerations will help you get started: Pressure range. Pressure media. Pressure generation options. Weight increments. Accuracy.
Calibration. A deadweight tester is a proven method of pressure calibration that is usually chosen for bench applications when accuracy and reliability are the top requirements. Calibrations are performed at the bench for convenience and to maintain reference conditions.

A dead weight tester is a precision instrument designed to calibrate pressure gauges by applying known weights to generate precise pressure values. It operates based on the fundamental principle of Pascal’s law, which states that pressure is directly proportional to force applied over a given area. How Dead Weight Testers Work.
