Piston dead weight tester

JY series Pressure Calibration pump piston Deadweight tester  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 materials, 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.
