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

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
