First Side working involvement

After getting the safety equipment, finally we are allow to follow the engineers to work at the side. This time is a 21MBR10CP calibration (pressure transducer calibration). According to the engineers, the pressure transducer calibration need to be checked at least once a year to make sure the pressure transducer's switch is able to disconnect at the correct pressure, 50mbar.

The engineers unplug the pressure transducer and inject pressure to it. Later, they check the disconnect pressure and adjust it to the correct scale. There are three transducers that need to be checked, after watching the engineers doing that, they allow us to hands on for the last transducer, and this is a precious opportunity for me to learn and experience. After checking all three transducers, they attach them back to the machine.




After performing all this work, we go back to the control room, the engineers explain to us that the function of the transducer. They are used for the 2 out of 3 protection system, which means, if two of them show high pressure, the system will trip on its own.



This is what we learn during this calibration check out and we are very lucky to have mr. Tawang who are willing to teach us.
