Dead weight piston gauge
WebA dead weight tester (DWT) is a calibration standard method that uses a piston cylinder on which a load is placed to make an equilibrium with an applied pressure underneath the … WebMost Dead-weight Testers have piston-cylinder units made of steel and/or tungsten carbide and their areas change by between about 9 to 27 parts per million per degree Celsius. For high quality measurements it is thus important to measure the temperature of the piston-cylinder in order to apply a temperature correction.
