Features:

• The piston and cylinder are made of high strength, high stiffness, and low temperature coefficient of linear

expansion of the carbide grinding tungsten carbide material , with a wide range of ambient temperature , stable

performance 20 ± 5 ℃.

• The load center of gravity low, weight by Cradle applied directly to the piston,the piston smooth operation, the

pressure fluctuation is extremely small, accurate indication.

• When pressure more than 25MPa ,the medium uses a small viscosity isooctyl sebacate, thus ensuring a very

high sensitivity.

• The weights used are all non-magnetic stainless steel material.
• The piston displacement sensor used to monitor the working position, the piston up and down stroke

of ± 1.5mm, instrument display is sensitive, smart, and accurate.

• Wide range, at the lower 1MPa, the basic error of ± 0.02% or ± 0.05%, a JY100 type manometer, capable of

reaching the upper limit of the current domestic 6,60,100MPa three measuring manometer.

• pressure regulator easy , even at 250MPa pressure could ease.

Application:

Piston gauges are used to calibrate customer piston gauges and pressure sensing devices
