YUNYI 5-500Mpa Ultra high pressure Dead Weight Tester Calibration

5-500Mpa Ultra high pressure Dead Weight Tester Calibration For Oil Industry

Description of JY series dead weight tester

JY series Digital pressure gauge piston dead weight tester calibration for oil industry with 100Mpa high pressure. JY SERIES piston pressure gauge is a new product developed by our company according to the latest "Piston PRESSURE gauge" inspection regulations (JJG59-2007). The key components of the piston gauge use tungsten carbide material with high hardness and low coefficient of linear expansion temperature, which improves the wear resistance of the piston, so the deformation under pressure is very small (negligible), and the performance is extremely stable. The working medium is piston type isoctyl sebacate, so the pressure gauge has high sensitivity.
Due to the adoption of new materials, new technology, new technology, new piston pressure gauge technical indicators have been greatly improved. Therefore, it is widely used to test digital pressure gauge, precision pressure gauge, pressure transmitter, pressure sensor and other pressure instruments.

Specifications

Features & Application

Typically dead weight testers are used in calibration laboratories to calibrate 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 adjustment easy , even at 500MPa pressure could ease
