How does a deadweight tester work
WebMay 31, 2024 · The basic equation for the deadweight tester is: P = F/A. P = the pressure being derived. F = the force applied by the weights. A = the effective area of the piston cylinder. PL = PA x GL/G. PL = Actual Pressure at the local gravity of the test site. PA = Actual Pressure as shown in the Calibration Report. How do dead weights work? WebTo perform gauge and/ or differential pressure calibrations, two deadweight testers floating at the nominal pressure are required, which adds the uncertainty on the pressure as well as reference side of the differential sensor.
