Deadweight tester JY

JY series piston gauge is our new R & D product manufactured according to the latest national “piston gauge” test procedures (JJG59-2007). The key components of piston gauge uses a tungsten carbide material with a high hardness and low temperature coefficient of linear expansion, which improving the wear resistance of the piston,therefore only a little (negligible )deformation under the pressure, performance is extremely stable. Working medium with a piston isooctyl sebacate, so pressure gauge with high sensitivity.As a result of new material s , new technologies , new processes,the technical indicators of new piston gauge has been greatly improved. Thus widely used to test digital pressure gauge,precision pressure gauges, pressure transmitters, pressure sensors and other pressure instruments. 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.
