Description 5~250MPa Oil Operated Hydraulic Pressure Dead Weight Tester
Pressure Gauge
5~250MPa oil operated hydraulic pressure dead weight tester
pressure gauge 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 5~250MPa Oil Operated Hydraulic Pressure Dead Weight Tester
Pressure Gauge
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.
