Frequently Asked Questions

What does this probe measure?

It is primarily used to measure radial vibration, axial position, and speed of rotating machinery shafts.

How do I set the correct gap?

For radial vibration, typically set the probe gap voltage between -9 Vdc and -10 Vdc.

Can it be used on high-speed or high-temperature equipment?

Yes. Its wide temperature range and rugged design suit gas turbines, steam turbines, and similar demanding applications.

Any important installation notes?

Ensure the probe mounting hole is perpendicular to the shaft surface. Secure firmly with the lock nut after installation.

What is a common mistake based on experience?

Forgetting to securely reconnect the ClickLoc connector after maintenance. Listen for the audible “click” to confirm full lock.
