60mpa Hydraulic Dead Weight Tester Calibration Bench Pressure Calibrators

Description 60mpa Hydraulic Dead Weight Tester Calibration Bench Pressure Calibrators

Deadweight tester (DWT) is a calibration standard which uses a piston cylinder on which a load is placed to make an equilibrium with an
applied pressure underneath the piston.Deadweight testers are so called primary standards which means that the pressure measured by a deadweight tester is defined through other quantities; Length, mass and time.Typically deadweight testers are used in calibration laboratories to calibrate pressure transfer standards like electronic pressure measuring devices.

Features 60mpa Hydraulic Dead Weight Tester Calibration Bench Pressure Calibrators

1. Fully comply with JJG59-2007 "Piston Pressure Gauge", JJG99-2006 "Weight" national metrological verification regulations, and use the piston pressure gauge launched by our factory's 50-year core technology.
2. The piston and piston cylinder are made of alloy steel, tungsten carbide and other materials with high strength, high hardness and low temperature coefficient of linear expansion. Piston pressure gauges have extremely high sensitivity.
3. The piston and piston cylinder are finely ground, and their roundness error and clearance are extremely small. The working medium adopts low-viscosity sebacic acid, which greatly increases the duration of the piston rotation, and correspondingly reduces the piston descending speed and increases the speed of the piston. Piston discrimination.
4. For the needs of verification work, the effective area of ​​the piston is relatively small, so the total weight of the weight is relatively light, saving labor intensity.
5. The pallet is used for direct loading, which avoids additional vertical force, reduces the center of gravity of the weight, and correspondingly reduces the additional lateral error of the weight.
6. Make the piston rotate more smoothly.
7. The working position of the piston is monitored by a displacement sensor, which has the advantages of being sensitive, eye-catching and accurate.
The weights have been corrected for pressure deformation coefficients and local gravitational accelerations.
8. When submitting for inspection, only the piston measuring system is required for inspection, which is small in size and light in weight.
