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.

| Type | YS Piston | KY Piston | DK Piston | Difference |
| Piston System Material | Alloy Steel (Hardness 28) | Tungsten carbide (hardness102) | Tungsten carbide (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 |
