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.

Advantages dead weight tester pressure gauge calibration
Feature china dead weight tester pressure gauge calibration
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.
