Description ys-2.5 dead-weight prssure tester deadweight tester calibration yjy-600


 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.also 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 device

Features of YUNYI ys-2.5 dead-weight prssure tester deadweight tester calibration yjy-600

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.

The pistons and piston barrels are ground by precision, their roundness errors and gaps are very small. The working medium adopts sebacic acid ester with low viscosity, which greatly increases the duration of the piston rotation, correspondingly reduces the piston's descent speed, and improves the piston identification. 

The effective area of the piston is relatively small, so the total mass of the weight is relatively light and the labor intensity is saved.

The tray is directly loaded to avoid additional vertical forces, reducing the weight center of gravity, and correspondingly reducing the lateral additional error of the weight. Make the piston turn more smoothly.

The working position of the piston is monitored by a displacement sensor, which has the advantages of being sensitive, eye-catching and accurate. Weights have been corrected for pressure deformation coefficients and local gravitational acceleration.

When the inspection is performed, only the piston measurement system is required to be inspected, which is small in size and light in weight.
