(A) Producing high pressures

(B) Testing magnitude of the given weight

(C) Calibration of other equipment

A dead weight tester is used widely for calibration of other equipment. Dead weight tester is a device that measures pressure by dividing the force’s weight by its applied surface area. Through the use of calibrated weights set atop a hydraulic piston, it produces pressures that are extremely exact.

It has the ability to generate a test pressure for the calibration of many pressure sensors as well as measure the pressure exerted by gas or liquid. When applied pressure and the reference weight (pressure) are equal under this circumstance, the reference weight will be zero. We first place the weight on the calibrating weight stand (Dead). As a result, it is known as a dead weigh tester.

• Both its construction and use are straightforward.
• A variety of pressure measuring instruments can be calibrated using it.
• Simple adjustments to fluid pressure can be made by modifying the piston-cylinder configuration or adding weights.

Limitations: The friction between the piston and cylinder, as well as the unknown value of the gravitational constant g, both have an impact on the deadweight tester’s accuracy.

Summary:

## A dead weight tester is used widely for_____? (A) Producing high pressures (B) Testing magnitude of the given weight (C) Calibration of other equipment (D)Accurate measurement of loads

Many pieces of equipment are calibrated using a dead weight tester. It is a tool that calculates pressure by dividing the force’s weight by the surface area where it is applied.
