Description Hydraulic Pressure Gauge Calibration Dead Weight Tester
Calibrator Price For Sale
The deadweight tester (DWT) is a calibration tool that utilizes a
piston cylinder and a placed load to establish equilibrium with an
applied pressure beneath the piston. As a primary standard, the
pressure measured by a deadweight tester is defined through other
fundamental quantities such as length, mass, and time. These
testers are commonly utilized in calibration laboratories for
calibrating pressure transfer standards, including electronic
pressure measuring devices. The deadweight tester is a reliable and
accurate method for calibrating pressure instruments and ensuring
that they provide accurate and precise measurements. Its use is
essential for maintaining the accuracy and reliability of pressure
measuring equipment used in various industries.

Features Calibration Standard JQ Hydraulic Pressure Piston Dead
Weight Tester Pressure Calibrator 10000 Psi Yunyi
The piston and its barrel are composed of high-strength alloy
steel, tungsten carbide, and other materials with low temperature
linear expansion coefficients, ensuring minimal deformation and
high sensitivity to pressure changes.
Precision grinding ensures minimal roundness errors and gaps, while
the use of low viscosity sebacic acid ester as the working medium
increases piston rotation duration and improves identification. The
small effective area of the piston results in a relatively light
weight, reducing labor intensity. Direct loading of the tray
reduces vertical forces and lowers the weight center of gravity,
leading to smoother piston rotation. Monitoring of the piston's
working position with a displacement sensor enables sensitive and
accurate measurements, with corrections made for pressure
deformation coefficients and local gravitational acceleration.
Additionally, the compact and lightweight design of the piston
measurement system simplifies the inspection process.
