Piston Dead weight tester pressure gauge tester 0.04~0.6Mpa Accuracy 0.02
Description
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.

Features
1. Piston and piston cylinder are using high strength, high hardness, and low temperature expansion coefficient of tungsten carbide material after, the working environment temperature is wide, stable performance of 20±5℃.
2. The load center of gravity is low, the weight is directlyadded to the piston through the hanging basket, the piston runs smoothly, the pressure fluctuation is very small, and the value is accurate.
3. Above 25MPa, pressure transmitting medium use diisooctyl sebacate with small viscosity, to ensure a high sensitivity..
4. The weights of the tester is made of stainless steel.
5. Piston position with displacement sensor monitoring, the piston up and down stroke is ±1.5mm, the instrument display has the advantages of sensitive, eye-catching, accurate and so on.
6. Range wide, at the lower limit of 1MPa, the basic error is ±0.02% or ±0.05%, a KY100 type tester, can replace 3 testers of 6,60,100MPa.
7. It is labor saving, and can be easily to add pressure to be 100MPa.
Specification
1. Measurement range and accuracy
At ambient temperature(20±2)℃, the temperature fluctuation is not more than 0.5℃ reference Table 1.

Material
| Type | YS Piston | KY Piston | DK Piston | Difference |
| 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 |
