YS series deadweight tester


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.
