3201 Lecture 2: Report on Dead weight tester 2
Document Summary
The dead weight tester apparatus is made up of a chamber filled with oil-free impurities and a piston-cylinder combination mounted above the chamber, as shown in the diagram. The top of the piston is equipped with a platform for carrying weights. To control the pressure of the oil in the chamber, a plunger with a handle has been provided. The pressure gauge to be tested is mounted on a suitable plate. A dead weight tester is essentially a pressure producing and measuring device. It is utilized in the calibration of pressure gauges. Calibrating a pressure gauge with the deadweight tester. To calibrate a pressure gauge with the deadweight tester, set up the device a flat surf. Proceed with the calibration according to the following steps: As shown in the diagram above, connect the pressure gauge to the test port on the dead weight tester.
