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
