330105-02-12-20-12-05 | Bently Nevada | 3300 XL 8 mm Reverse Mount Probes

### Product Description
This is a reverse-mount eddy current proximity probe designed for integration with Bently Nevada 3300 XL monitoring systems. It features an 8 mm sensing diameter and mounts from the rear of the housing to simplify installation in space-constrained machinery.
Moreover, it delivers high-fidelity shaft displacement and vibration measurements for continuous condition monitoring of rotating equipment. Therefore, it is commonly deployed on steam turbines, compressors, and large electric motors where mechanical integrity must be verified in real time. In addition, its robust construction supports operation in harsh industrial environments with temperature extremes and electromagnetic interference.

### Technical Specifications

### Typical Applications
– Steam turbine shaft position and axial thrust monitoring
– Centrifugal compressor radial vibration measurement
– Large motor rotor eccentricity and bearing wear detection
– Gearbox input/output shaft displacement tracking

### FAQ
What is the standard output sensitivity for this probe?
The probe has a nominal sensitivity of 7.87 V/mm (200 mV/mil) at 10 kHz, calibrated per API 670.

Is this probe compatible with legacy 3300 series monitors?
Yes, it is fully compatible with all 3300 series monitors and preamps, including 3300 XL and earlier 3300 non-XL systems.

Does the reverse mount configuration require a special extension cable?
No—standard 3300 XL coaxial extension cables (e.g., 330130-01-00-10-00) are used; no adapter or modification is needed.

What is the operating temperature range?
The probe operates continuously from –30 °C to +120 °C (–22 °F to +248 °F) in ambient conditions.

Can it be used in hazardous areas?
No—this probe is not intrinsically safe or explosion-proof; use only in non-hazardous locations unless paired with appropriate certified barriers.
