The Piston Dead Weight Tester, used for pressure calibration, is a primary standard apparatus employing a piston-cylinder mechanism. It establishes equilibrium between the applied load and the pressure beneath the piston. This device is considered a primary standard as its pressure readings are based on fundamental quantities like length, mass, and time. It is primarily used in calibration labs for calibrating pressure transfer standards, including electronic pressure measuring devices. By providing a reference pressure traceable to basic physical quantities, it ensures the accuracy and reliability of pressure measurements across various applications.

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.
