Product Description
Stainless steel dead weight tester
Description:
JQ 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.
Specifications:
Measure range: 0.04`0.6MPa, 0.1`6MPa, 0.5`25MPa, 1`60MPa, 2`100MPa, 2`160MPa, 5`250MPa
Accuracy: 0.005, 0.01, 0.02, 0.05.
Function: used to calibrate digital pressure gauge, precision pressure gauge, pressure transmitter etc.
Material: tungsten carbide
Weight: No magnetic metal materials (0.005, 0.01, 0.02); carbon steel (0.05)
Features:
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 |
workbench | Cast iron workbench | Cast aluminum workbench | Cast iron workbench | Cast iron workbench with low cost and high hardness |
