Bently Nevada 330105-02-12-15-12-05 Full Technical Overview
1. Product Title
330105-02-12-15-12-05 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 predictive maintenance systems for rotating equipment.
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 330105-02-12-15-12-05 is an 8 mm reverse mount proximity probe designed for continuous monitoring of rotating machinery condition.
It uses eddy current sensing technology, enabling non-contact measurement of the distance between the probe tip and conductive metallic shaft surfaces.
The reverse mount configuration is mainly used where installation space is limited or where traditional axial mounting cannot be applied.
This probe is typically part of a full monitoring system consisting of:
- Proximity probe
- Extension cable
- Proximitor signal conditioner
Together, they form a complete machinery protection chain for vibration and displacement monitoring.
