Hydraulic dead weight tester pressure balance
Description Hydraulic dead weight tester pressure balance
Deadweight tester (DWT) is a calibration standard which uses a piston cylinder on which a load is placed to make an equilibrium with an applied pressure underneath the piston.
Deadweight testers are so called primary standards which means that the pressure measured by a deadweight tester is defined through other quantities; Length, mass and time.
Typically deadweight testers are used in calibration laboratories to calibrate pressure transfer standards like electronic pressure measuring devices.

Specification Hydraulic dead weight tester pressure balance
Features Hydraulic dead weight tester pressure balance
The piston and the piston barrel are made of alloy steel, tungsten carbide and other materials with high strength, high hardness and low temperature linear expansion coefficient. The temperature expansion coefficient is small and the deformation is small, thus ensuring that the effective area of the piston has a small periodic rate of change to ensure the piston pressure. With extremely high sensitivity.
