Product Overview
The 330105-05-30-10-02-CN 3300 XL 8 mm Reverse Mount Probe from Bently Nevada is a displacement measurement sensor designed for reverse mounting configurations in rotating machinery protection systems. This probe is used in turbines, compressors, pumps, generators, and heavy industrial rotating equipment operating in refinery, petrochemical, power generation, and mining environments where continuous vibration and shaft position monitoring is required to prevent unexpected mechanical failure.
This model is part of the 3300 XL proximity transducer system and provides stable eddy current-based measurement for shaft vibration and position feedback. The reverse mount design supports installation in constrained mechanical spaces where standard forward mounting is not feasible. The system helps reduce downtime by enabling accurate non-contact measurement of shaft movement under high vibration, oil exposure, and temperature variation conditions.

Probe Design and Material Configuration
The 330105 reverse mount probe uses a polyphenylene sulfide (PPS) probe tip designed for mechanical stability and resistance to industrial contamination. The probe case is constructed from AISI 303 or 304 stainless steel to ensure corrosion resistance in harsh operating environments such as offshore platforms, refinery units, and compressor stations.
The ClickLoc connector system provides secure electrical engagement and reduces installation errors during field replacement. The reverse mount geometry allows installation flexibility in compact machine housings where axial alignment constraints limit conventional probe placement.
This probe is fully compatible with Bently Nevada 3300 XL monitoring systems and maintains standardized calibration behavior across existing proximitor modules.

Installation and Engineering Recommendations
Install the probe in a rigid mounting structure to ensure stable shaft alignment and accurate gap measurement under continuous vibration conditions.
Maintain correct probe gap calibration during commissioning using system proximitor settings to avoid unstable signal output or incorrect vibration readings.
Use shielded extension cables and route wiring away from high-voltage motor cables and VFD outputs to minimize electromagnetic interference in industrial environments.
For high-temperature applications, ensure sufficient thermal clearance between probe body and heat sources to maintain long-term measurement stability.
