Another Calibration

Yesterday we learn about pressure transducer calibration, today we had the opportunity to do another one. This pressure transducer is different with the one before, it is a mechanical instrument which called c-bourdon. It used the concept just like the party favor, when the pressure enter the c-bourdon, it will try to straighten out, as a result, it will pull the pointer to the correct scale.



what the engineer do today is to calibrate the pressure transducer. Similarly, engineer attach the handpump and multifuntional calibrator together, and inject pressure. Multifunctional calibrator as reference, they check the scale of c-bourdon. Adjustment is done when necessary.



The c-bourdon shows some error reading, after some maintenance, the error is acceptable. lastly, they attach back the pressure transducer back to the turbine.
