Instrumentation commissioning involves checking, inspecting, testing, and configuring equipment to ensure it’s ready for operation.

Instrumentation commissioning

Here are some critical points to check during commissioning of industrial instrumentation:

  1. Documentation: Ensure that all relevant documents are available and updated. This includes P&IDs, loop diagrams, wiring diagrams, device datasheets, and configuration details.
  2. Physical Inspection: Verify the physical installation of the instruments. Check for correct mounting, proper alignment, and secure connections. Inspect for any visible damages or loose fittings.
  3. Wiring and Connections: Check all the wiring connections for correctness and firmness. Ensure the wiring is as per the schematics and loop diagrams.
  4. Power Supply: Confirm the power supply to each instrument is correct and stable. Check voltage levels and power source continuity.
  5. Configuration: Verify the configuration settings of each instrument. This includes checking the set points, ranges, alarms, control actions, etc. Ensure they align with the process requirements and the instrument datasheet.
  6. Signal Verification: Confirm the signals from the instruments. This could be 4-20mA for analog signals or the specific protocol messages for digital communication.
  7. Calibration: Perform a calibration check on the instruments to ensure they are reading correctly. Use a known source for calibration and compare the instrument reading with the source.
  8. Loop Check: Conduct a loop check to confirm that the signal from each instrument correctly reaches its destination (like the control room or the PLC).
  9. Functionality Tests: Test the functionality of each instrument. This could include checking the response to changes in process conditions, testing alarms, control actions, etc.
  10. Communication: Check the communication of instruments with the control system, and confirm correct data transmission.
  11. Safety Checks: Perform safety checks as per local regulations and company policies. This includes checking for proper grounding, insulation, etc.

Remember, the exact checklist for commissioning can vary depending on the specific instrumentation, the process requirements, and local regulations. Always follow the manufacturer’s guidelines and consult with an experienced professional if in doubt.
