Frequently Asked Questions

• What does “differential expansion” mean?
• It measures the growth difference between a rotor and its casing during machine start-up or shutdown.
• Why are two channels important?
• Two channels let you monitor both ends of a rotor. This gives a complete picture of machine health.
• How does high accuracy help my operation?
• Early detection of small changes allows planned maintenance. This prevents unexpected downtime and costly damage.
• Can this unit operate in very cold locations?
• Yes. Its rated from -40°C. In very cold sites, ensure signal cables are rated for low temperature to prevent stiffening.
• How do I choose the right monitor for my machine?
• First, know your expected expansion range. This 0-10mm model suits many turbines. Always check machine OEM specifications for required range and accuracy.
