DEADWEIGHT TESTER WEIGHTS

摘要

A weight set for applying a deadweight in the fluid-supported piston of a pressure test set to produce a proportionate pressure in the supporting fluid. The weight includes a circular baseplate disposed for rotation around the cylinder of the test set and provided with an axial rod for engaging the piston. The weight set is spun around the piston to overcome static friction and provide a steady pressure in the fluid. A number of hollow cylinder weights are secured to the plate to provide a high moment of inertia per mass and achieve an appreciable spin time for accurate reading of the fluid pressure.
