Loop Checking

Loop checking is a critical step in the commissioning process that verifies the integrity and functionality of instrumentation loops from field device to control system and back.

What is Loop Checking?

Loop checking involves testing the complete signal path from field instruments through junction boxes, marshalling panels, and I/O cards to the control system. This includes verifying:

• Signal integrity and calibration
• Correct wiring and terminations
• Control system configuration
• Alarm and trip setpoints

Our Approach

Our experienced engineers systematically test each loop to ensure it operates correctly before plant startup. We document all findings and provide comprehensive loop test records for your quality management system.

Early identification of wiring errors, configuration issues, or faulty equipment prevents costly delays during hot commissioning.
