A dead weight tester apparatus uses unknown traceable weights to apply pressure to a fluid for checking the accuracy of readings from a pressure gauge. A 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 piston. Deadweight testers are so called primary standards which means that the pressure measured by a deadweight tester is defined t… WebMar 1, 2024 · 11/15/2013. Apr 12, 2006. #7. Glycerine would be used for testing gauges used in the oxygen field. Oil in an oxygen gauge could cause an explosion. My tester has been happy with 10w engine oil. Heavier oils made it lethargic. Regarding seals, last I knew, the weight platform/piston on these things have no seals. Tis only a precision fit.
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.
WebTo calibrate the gauge, students add weights to a platform on a dead weight tester. The weights put a known force on to a piston. The piston has a known area, so students can calculate the pressure.
