Gauges Calibration Methods

Pressure gauges can be calibrated with one of the following methods:

  1. Using Dead weight tester by calculating the actual pressure generated with the help of area of the piston, local ‘g’ and applied known mass while comparing.

  2. Using Dead weight tester by comparison method using the nominal pressure values mentioned on the pressure weights of the Dead weight tester.

  3. Using Digital Pressure Calibrator.

  4. By comparison method using a Digital /analog pressure gauge and pressure generating system.

Method I: Reading as per set on DUC

Method II: Reading as per set on standard

Hi, May i know what brand of dead weight tester you using?
