Hydraulic piston dead weight tester

YS series Piston DWT is a high accuracy high reproducibility and high reliability of the standard pressure measuring instruments based onPascal's law and the principle of hydrostatic equilibrium produced. Mainly used for measuring room, laboratory and production as part of scientific experiments, or use a reference pressure. The working principle of YS dead weight tester is based on the piston itself weight, and add the dedicated weights on piston weight, the pressure produced on the piston area and the hydraulic pressure balance status of the container. Piston dead weight tester composed of the two part test pump and measuring system. 1.
