JY Series Digital Piston Pressure Gauge Dead Weight Tester Pressure Calibration pump piston Deadweight tester
Description of JY series dead weight tester
JY series Pressure Calibration pump piston Deadweight tester is our
new R & D product manufactured according to the latest national
"piston gauge" test procedures (JJG59-2007). The key components of
piston gauge uses a tungsten carbide material with a high hardness
and low temperature coefficient of linear expansion, which
improving the wear resistance of the piston,therefore only a little
(negligible )deformation under the pressure, performance is
extremely stable. Working medium with a piston isooctyl sebacate,
so pressure gauge with high sensitivity.
As a result of new materials, new technologies, new processes,the
technical indicators of new piston gauge has been greatly improved.
Thus widely used to test digital pressure gauge, precision pressure
gauges, pressure transmitters, pressure sensors and other pressure
instruments.

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 JY100 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.
Applications
The pistons and piston cylinder is made of the carbide tungsten
carbide materials which has high strength, high hardness, and low
temperature , so,it has wide working temperature and stable
performance of 20 + / - 5 ℃.
Random error ±0.02% or ±0.05%
The weight of the pressure gauge is made of stainless steel
The piston top and bottom moves ±1.5mm
The piston runs smoothly, the pressure fluctuation is minimal and
the value is accurate.
Applications of Digital Piston pump pressure Dead Weight Tester:
Piston gauges are used to calibrate customer piston gauges and
pressure sensing devices
