Bently Nevada 330105-02-12-20-02-05 Full Technical Overview
1. Product Title
330105-02-12-20-02-05 3300 XL 8 mm Reverse Mount Proximity Probe
2. Brand
This product belongs to a globally recognized industrial condition monitoring and machinery protection technology brand widely used in vibration monitoring, shaft displacement measurement, and rotating equipment protection systems.
3. Product Series
3300 XL 8 mm Proximity Transducer System (Reverse Mount Type)
This series is designed for high-precision non-contact measurement of shaft vibration and position in critical rotating machinery such as turbines, compressors, pumps, and motors.
4. Product Introduction
The 330105-02-12-20-02-05 is an 8 mm reverse mount proximity probe designed for continuous condition monitoring of rotating equipment.
It uses eddy current displacement sensing technology, enabling non-contact measurement of the gap between the probe tip and conductive shaft surfaces.
The reverse mount design is intended for tight mechanical spaces or installations where conventional axial probe mounting is not possible.
This probe is normally used as part of a complete 3-component system:
- Proximity probe
- Extension cable
- Proximitor signal conditioning module
Together, they form a stable vibration monitoring chain for industrial protection and predictive maintenance systems.
