Piston Dead weight tester /pressure gauge tester
Description: Piston Dead weight tester /pressure gauge tester
KY series DWT is a high precision and reliable standard pressure calibrator which is basic on Pascal law and a statics balance principle. It is usually called piston gauge or manometer, sometimes pressure balance instrument, major used in the lab and measure workshop, or as a pressure calibrator. Sometimes, we use it on some other gauges to calibrate the data.

| Piston System Material | Alloy Steel (Hardness 28) |
(hardness102) |
(hardness102) |
Alloy steel easy wear, high deformation coefficient, high pressure errors increase Tungsten carbidemore harder, less temperature coefficient, wear resistance, but brittle |
| Weighing plate style | Bearing plate | Basket | Bearing plate |
Basket for lower center of gravity, add weights need both hands to operate, low efficiency. Bearing plate only need one hand to put the weights, can calibrate faster. |

Piston Anti-breaking device |
With guide rod anti-break | Without guide rod easy break | With guide rod anti-break | Anti-breaking device will sacrifice fall delay of the piston and other parameters, but will protect the piston rod , more practical. |
| Pre-pressurizing device | without | with | Option (electric pre-pressurized) |
Pre-pressurization is mainly used when the customer needs to connect more oil-filled pipes and equipment achieve oil filled function. Common check does not require pre-pressurized. |
| Displacement indications | Scale displacement indications | Single digital indication |
Scale indication (lighting instructions optional) |
Physical scale indication may be out of power constraints, digital indication more intuitive , both have their advantages, JQ type can have two kinds of instructions for simultaneous, can also be used when power off. |
| Pressurization System | Traditional screw pressing pressure |
Self-lubricating pressurized cylinder No need replacing seals |
Small-diameter pressurized screw, need replace the seals, but longer life |
Traditional screw pressurized , especially hyperbaric pressure too tired. Self-lubricating pressure more easy. Small-diameter pressurized cylinder in the middle position |
| Base | Cast iron base | Cast aluminum base | Cast iron base |
Cast iron base,low cost,high hardness |
