Piston pressure gauge pressure calibrator dead weight tester
Description Piston pressure gauge pressure calibrator dead weight tester
Piston pressure gauge/pressure calibrator/dead weight tester 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 pressure calibrator/dead weight tester
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 directly added 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.
