Dead Weight Pressure Tester, 300 PSI, w/ NIST Traceable Certificate
Pressure calibration points produced by the deadweight tester are accurate to within ± 0.1% of the reading certified traceable to the N.I.S.T. The tester provides consistent, repeatable accuracy, maintaining its pressure for an appreciable length of time regardless of temperature changes, slight leaks in the pressure system, or changes in volume of the pressurized system due to movement of a Bourdon tube or other device.
The deadweight tester consists of a two stage hydraulic pump containing a manifold which is pressurized during operation. Integral to the pump is a shuttle valve that allows the operator to regulate the speed of pressure increase. One connection to the manifold includes a cylinder and a free-floating precision machined piston with a plate for holding calibrated weights. A second connection to the manifold accommodates a gauge or other pressure measuring device to be calibrated or checked. Incorporated into the manifold is a hand operated displacement valve that allows small adjustments in fluid volume to be made without further operation of the pump handle or release valve.
