As basic idea lang, read or surf about instruments (sensors, transmitters and switches) for pressure, temperature, vibration, flow, and speed. Actually daghan pa kaayo na pero mao na ang mga common. Para lang naa kay background daan.
Hatag ko ug example sa work sa instrumentation techs. Under ni sa maintenance department. During normal operation, mag preventive maintenance schedule like inspection if naay physical defects, erroneous reading, and if walay problem, cleaning lang.. assuming if it can be done online, or for some, the instrument to be PM'd will be bypassed or change-overed by a standby instrument or machine.
Then during pod sa corrective maintenance, if an equipment or machine failed, the instrument tech might check and troubleshoot if any instrument failed (there are times, the problem is not related with C&I but with electrical or mechanical). If there is a suspected instrument failure, sometimes an actual data, such as temperature or pressure gage, will be compared with the instrument transmitters reading. For swift corrective actions, the defective one will be replaced with new. Afterwards, the instrument technicians will check if the defective instruments can be repaired or not, and it is done at the laboratory or shop.
There are times that the problem is on the PLC or DCS cards. The instrument tech will replace the cards if one or more are defective. During replacement, the new card might be configured, usually ang configurations karon kay user friendly na, if maanad ka, mura nalang nag configure ka sa imong cellphone or PC.
Basta, instrument technicians are not necessarily engineering graduates. What's important lang is that you are trained with sufficient background. And don't worry, an instrumentation engineer or supervisor will be there to guide and lead you along the way.
