Specification Economic Digital Hydraulic Pressure Tester Piston Dead Weight Tester

Item YS Series KY Series JQ Series Difference
Material Alloy steel(hardness 28) Tungsten carbide
(hardness 102)
Tungsten carbide
(hardness 102)
Alloy is easy to wear, with big deformation
coefficient, high error when high pressure
Tungsten carbide with big hardness, small
temperature coefficient, wear resistance, but brittle
Anti-breaking
device
With guide rod for anti-breaking Without guide rod With guide rod for
anti-breaking
Anti-breaking device will reduce the piston
fall time, but can protect the piston rob,
more practical.
Pre-pressurizing
device
No Pre-pressurizing device With Pre-pressurizing device Optional (electric pre-pressurizing) Pre-pressurized mainly used when the
customer needs to connect more oil-filled
pipes and equipment. Usually it does not
require pre-pressurized.

replace the sealing ring
Small compression screw,
need to replace the sealing ring,
but with longer life
Traditional screw pressurized system need
more labour power.
Self-lubricating pressurize is very easy

Features  Economic Digital Hydraulic Pressure Tester Piston Dead Weight Tester

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 
Economic Digital Hydraulic Pressure Tester Piston Dead Weight Tester

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
