– Centrifugal compressor shaft displacement and differential expansion measurement
– Large electric motor rotor position and runout verification
– Hydroelectric generator bearing housing and thrust collar monitoring

### FAQ
What is the standard output sensitivity of this probe?
The probe has a nominal sensitivity of 4.0 V/mm (100 mV/mil) when used with a 3300 NSv monitor.

Is calibration required before installation?
Yes — each probe must be calibrated with its matching extension cable and monitor channel using the system’s calibration routine.

Can this probe operate in high-temperature environments?
It is rated for continuous operation up to +121 °C (250 °F); higher temperatures require thermal shielding or specialized variants.

What thread size is used for mounting?
The probe features a standard 3/8-24 UNF–2A threaded body for secure mechanical mounting.

Does it require an external power supply?
No — it receives power and signal conditioning from the connected 3300 NSv monitor via the extension cable.
