Pressure Switch Pressure Gauge Verifier Hydraulic Pressure Source

Description Pressure Switch Pressure Gauge Verifier Hydraulic Pressure Source

YS series Piston DWT is a high accuracy high reproducibility and high reliability of the standard pressure measuring instruments based on Pascal's law and the principle of hydrostatic equilibrium produced. Mainly used for measuring room, laboratory and production as part of scientific experiments, or use a reference pressure.
calibration standard which uses a piston cylinder on which a load is placed to make an equilibrium with an applied pressure underneath the piston.
The pistons and piston cylinder is made of the carbide tungsten carbide materials which has high strength, high hardness, and low temperature , so,it has wide working temperature and stable performance of 20 + / - 5 ℃.
The weight of the pressure gauge is made of stainless steel
The piston top and bottom moves ±1.5mm
The piston runs smoothly, the pressure fluctuation is minimal and the value is accurate.
Over 25MPa, Ensure the high sensitivity of the pressure gauge, we use the octyl sebacate as transmission medium
The pistons and piston barrels are ground by precision, their roundness errors and gaps are very small. The working medium adopts sebacic acid ester with low viscosity, which greatly increases the duration of the piston rotation, correspondingly reduces the piston's descent speed, and improves the piston identification.
The effective area of the piston is relatively small, so the total mass of the weight is relatively light and the labor intensity is saved.
The tray is directly loaded to avoid additional vertical forces, reducing the weight center of gravity, and correspondingly reducing the lateral additional error of the weight. Make the piston turn more smoothly.
The working position of the piston is monitored by a displacement sensor, which has the advantages of being sensitive, eye-catching and accurate. Weights have been corrected for pressure deformation coefficients and local gravitational acceleration.
When the inspection is performed, only the piston measurement system is required to be inspected, which is small in size and light in weight.

Features Pressure Switch Pressure Gauge Verifier Hydraulic Pressure Source

The piston and the piston barrel are made of alloy steel, tungsten carbide and other materials with high strength, high hardness and low temperature linear expansion coefficient. The temperature expansion coefficient is small and the deformation is small, thus ensuring that the effective area of the piston has a small periodic rate of change to ensure the piston pressure. With extremely high sensitivity.


Application Pressure Switch Pressure Gauge Verifier Hydraulic Pressure Source

Typically dead weight testers are used in calibration laboratories to calibrate pressure transfer standards like electronic pressure measuring devices
