FAQ

• Why is eccentricity monitoring important?
• It reveals shaft bow and misalignment early.
• Is this module used during startup?
• Yes. It is most valuable during slow roll.
• Can it reduce maintenance costs?
• Yes. Early warnings prevent major failures.
• What probe gap works best?
• Correct mid-range gap improves accuracy.
• How do I choose this over vibration monitors?
• Eccentricity focuses on shaft center, not vibration level.
