Description Hydraulic Pressure Gauge Calibration Dead Weight Tester
Calibrator Price For Sale
Deadweight tester (DWT) is a calibration standard which uses a pi
ston cylinder on which a load is placed to make an equilibrium wit
h an applied pressure underneath the piston. Deadweight testers are
so called primary standards which means t hat the pressure measured
by a deadweight tester is defined throug h other quantities;
Length, mass and time. Typically deadweight testers are used in
calibration laboratories t o calibrate pressure transfer standards
like electronic pressure mea suring devices.

Features Calibration Standard JQ Hydraulic Pressure Piston Dead
Weight Tester Pressure Calibrator 10000 Psi Yunyi
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.
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.
