dead weight tester pressure gauge calibration

Description dead weight tester pressure gauge calibration

The piston dead weight tester serves as a calibration standard machine, utilizing a piston cylinder that is loaded to establish equilibrium with the pressure beneath it. Dead weight testers are classified as primary standards, indicating that the pressure they measure is defined by fundamental quantities like length, mass, and time. These testers are typically employed in calibration laboratories for the purpose of calibrating pressure transfer standards, including electronic pressure measurement 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.
