Deadweight tester JY series

As the most important pressure reference instrument, the piston pressure gauge is mainly used to calibrate otherpressure instruments. t is one of the pressure reference instruments and the most cost- effective pressure reference equipment on the market, The piston pressure gauges produced by our factory are not only lt is our markepositioning for piston pressure gauges that it is limited to obtaining the national verification certificate, focusingmore on the convenience of measurement use, and making the measurement efficiency higher and easier. 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
