Product Description

Features
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 adjustment easy, even at 250MPa pressure could ease.

Applications
Typically dead weight testers are used in calibration laboratories to calibrate pressure transfer standards like electronic pressure measuring devices.
