5. What is instrumentation engineering?
 It’s the activities involved in providing the
instrumentation ( measuring
instruments/process control & logic
functions hardware and software / final
control elements )
Needed for proper operation of a process
unit, plant , or facility.

6. The keywords are “ proper operation”
Proper operation is the result of :
 Proper application of hardware
 Proper application of software
 Proper method of selecting hardware and
software
• Suitable for the project technical
requirements
• Ease of operation
• Ease of maintenance
• Ease of upgrade and / or expansion

7.  Proper review of manufacturer’s
engineering for the selected hardware &
software
 Proper review of inspection
manufacturer’s finished products before
shipment to site
 Proper installation
 Proper site check out and calibration
