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? WebA deadweight tester with automatic mass loading was the first step toward a solution to these problems. The instrument usually comprises of a loading mechanism operating in tandem with an external or internal controller to determine the optimal mass load for each measuring point.
WebThe Ametek HL Deadweight Tester extremely compact, self-contained portable tester is designed for pressure ranges from 10-200 psi (1-15 bar) up to 50-3,000 psi (5-225 bar). Accurate to ±0.05% of reading, the unit … WebHow Does A Dead Weight Pressure Gauge Work? In a deadweight tester, the force is supplied by a mass in a gravitational field on top of a piston with a specific cross sectional area. The fluid (pneumatic or hydraulic) under the piston is pressurized so the piston and mass “float” in equilibrium. Why Is It Called Dead Weight?
WebDeadweight tester calibration is the act of comparing the readings of a device under test, such as a pressure gauge, to the known pressures produced by precise weights.
