dead weight tester pressure gauge calibration

Description dead weight tester pressure gauge calibration

The piston dead weight tester is a calibration standard machine that employs a piston cylinder, where a load is applied to create an equilibrium with the pressure exerted underneath the piston. Dead weight testers are known as primary standards, indicating that the pressure measured by them is defined through other quantities, such as length, mass, and time. Commonly, these testers are utilized in calibration laboratories for the calibration of pressure transfer standards, like electronic pressure measuring devices.

1. The piston and cylinder are made of high strength, high stiffness, and low temperature coefficient of linear expansion of the carbide grinding tungsten carbide material , with a wide range of ambient temperature , stable performance 20 ± 5 ℃.
2. The load center of gravity low, weight by Cradle applied directly to the piston, the piston smooth operation, the pressure fluctuation is extremely small, accurate indication.
3. When pressure more than 25MPa ,the medium uses a small viscosity isooctyl sebacate, thus ensuring a very high sensitivity.
4. The weights used are all non-magnetic stainless steel material.
5.The piston displacement sensor used to monitor the working position, the piston up and down stroke of ±1.5mm, instrument display is sensitive, smart, and accurate.
6. Wide range, at the lower 1MPa, the basic error of ± 0.02% or ± 0.05%, a KY100 type manometer, capable of reaching the upper limit of the current domestic 6,60,100MPa three measuring manometer.
7. pressure regulator easy , even at 250MPa pressure could ease.
