Measure & Control InstrumentsDead Weight Tester


Dead weight testers

The operation of dead weight testers is based on the principle of balancing known weights against the force produced by an unknown pressure action on a hydraulic piston of known area. When these forces reach equilibrium and balance the unknown pressure equals the total of the weights and piston.

De Wit dead weight testers incorporate a built-in pump for generating pressure and can be used for checking spring gauges, calibrating bourdon gauges, recorders, transmitters or other instruments, pressure testing small vessels, and measuring gas pressure with high accuracy.

- Brass weights (optional stainless steel weights)

- Measuring units psi, bar, kPa or kg/cm2

- Supplied with metal carrying case(s)

Portable version with an accuracy of +/- 0.1% of rated pressure: pressure ranges from 500psi up to and including 15,000psi.

Laboratory version with an accuracy of +/- 0.05% (optional +/- 0.03%) of rated pressure: pressure ranges from 500psi up to and including 20,000 psi, electric motor drive 220V (optional 110V).

High pressure laboratory dead weight tester with an accuracy of +/- 0.1% for very high pressures: 25,000psi, 35,000psi and 40,000psi.
