### Product Description
This is a proximity probe designed for non-contact vibration and position monitoring in rotating machinery. It operates as part of the Bently Nevada 3300 XL series condition monitoring system.
Moreover, it delivers high-resolution displacement measurements for shaft radial vibration and axial position in turbomachinery. Therefore, it is routinely deployed in gas turbines, steam turbines, compressors, and large motors. In addition, its ruggedized construction supports operation in high-temperature, high-vibration industrial environments.

### Technical Specifications

### Typical Applications
– Gas turbine shaft vibration monitoring
– Steam turbine differential expansion measurement
– Centrifugal compressor axial position sensing
– Large motor rotor eccentricity detection
– Hydroelectric generator bearing housing displacement tracking

### FAQ
What is the standard output sensitivity of this probe?
It provides a nominal sensitivity of 4.0 V/mm (100 mV/mil) when used with a 3300 XL extension cable and monitor.

Is this probe compatible with legacy 3300 systems?
Yes, it is backward compatible with all 3300 series monitors and preamplifiers.

Does it require calibration before installation?
No—factory-calibrated; zero-shift verification is recommended during installation per API 670.

What is the maximum operating temperature?
The probe body is rated to 121°C ambient; higher temperatures require heat shields or specialized mounting.

Can it be used in hazardous areas?
Only when installed with an approved intrinsically safe barrier and certified system components.
