Description Economic Digital Hydraulic Pressure Tester Piston Dead Weight
Tester
Piston dead weight tester is our fourth generation product, this
product is based on YS piston tester and KY piston tester, with a
cost-effective, anti-off mechanism for piston systems, greatly
reducing the harm caused by improper operation.

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. |
Displacement
directions | Scale displacement
indications | Digital displacement
indications | Scale displacement indication
(Optional lighting instructions) | Physical scale indication can be from the
shackles of electricity, figure indicates more
intuitive, both have their advantages, JQ type
can have two kinds of instructions. |
Pressurization
system | Use traditional
compression screw | Self-lubricating pressurized
cylinder without having to
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
Small caliber pressurized cylinder in the middle |

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
