Deadweight testers are pressure calibration devices that use known, traceable weights and precision machined piston and cylinder assembly to check the accuracy of pressure gauges, sensors, transmitters, and transducers. With unmatched accuracy, stability, and repeatability; deadweight testers are universally accepted as the standard for ...
Oct 19, 2021 · Dead weight testers are instruments that are used to calibrate pressure gauges. Calibration using the dead weights method is known to have high accuracy and hence is also called the primary standard when it comes to accurate measurement of pressure. This calibration method using dead weights is done on the basis of formula and can be used to ...
Today, dead weight testers are mainly used by standards laboratories to provide a reference standard for pressure calibration purposes. The introduction of more accurate and more efficient electronic based calibration equipment in recent years has caused a significant reduction in the number of dead weight testers used throughout industry.
Deadweight Testers. We provide the world’s only ball-type deadweight testers, where the ball and weights float on a thin film of air, which is virtually frictionless. This design eliminates the necessity to rotate the weights during testing, and allows the user to concentrate on the instrument itself. Our testers are engineered to offer user ...
Dead weight Tester consists of an accurately machined piston of known weight which is inserted into a closed fitting cylinder of known cross-sectional area. Weights of known mass are loaded on one end of the piston and the fluid (Air/Oil/Water) pressure is applied to the other end of the piston until enough force is developed to lift the piston.
The deadweight tester conveniently provides all three of these functions in one integrated instrument. (see Figure 2). Figure 1. High-pressure instruments, such as the analog gauge pictured here, are often calibrated using hydraulic test media. Figure 2. A conventional deadweight tester generates, controls, and measures hydraulic pressure.
Deadweight Testers (DWT) are the primary standard for pressure measurement. There are three main components of this device: a fluid (oil) that transmits the pressure, a weight and piston used to apply the pressure, and a connection port for the gauge to be calibrated.
