WebAshcroft® hydraulic deadweight testers are primary pressure standards that derive their accuracy directly from principles of physics and maintain it for an extended period of time. Pressure gauge comparators are secondary standards that use the same hydraulic test pump to generate pressure, but compare to high accuracy “master” test gauges ... Web3.2.1 Hydraulic Piston-Cylinder Deadweight Testers. The equipment, as illustrated on Figure 3-1, consists of four identical column assemblies to hold the master piston and cylinders and one identical column to hold the piston and cylinder under test. Each of the master columns contains a master piston of a single range (0.01,0.020,.05,0.1in2 ...
