Calibration of chemical process control instruments
Thread Content
Colleagues, I have a question: how exactly are chemical process control instruments (such as those for pressure, temperature, level, and valves) calibrated? ? Should it be done by the factory’s own instrument technicians, or by a qualified third-party agency? How do I work as a machinist? Are qualifications required? ? Will the instrument technician be held legally responsible if an accident occurs as a result of their actions? ?

Check the list of instruments subject to mandatory calibration at the local metrology testing institute! Those required to undergo mandatory calibration must go to a metrology testing facility for such calibration; those not required can seek calibration or adjustment from a qualified metrology testing facility or a third-party calibration agency.
There are also those who ask that verifying instruments is a basic skill for instrument technicians. Of course, those that fall under the category of mandatory inspection are sent to qualified inspection agencies for testing – this is common sense.
