Top Instrumentation Errors to Avoid Before Plant Start-Up
Even a small mistake during instrumentation commissioning can lead to false readings, trips, or costly downtime. Check these common pitfalls before energizing your system:
Skipping Loop Checks – Signals not verified → wrong readings.
Calibration Only in Workshop – Must calibrate on-site.
Wrong Impulse Line Installation – Incorrect slope → false pressure readings.
Incorrect Signal Type – 4–20 mA vs 0–10 V errors → control issues.
Wiring Not Matching Drawings – Prevents instruments from working.
Forgetting Valve Stroking – May cause functional failure.
No Simulation of Real Conditions – Test under actual process conditions.
