Bently Nevada 330105-02-12-20-05-00 Full Technical Overview
1. Product Title
330105-02-12-20-05-00 3300 XL 8 mm Reverse Mount Proximity Probe
2. Brand
This product belongs to a globally recognized industrial condition monitoring technology brand widely used for vibration monitoring, shaft displacement measurement, and rotating machinery protection systems in power generation, oil & gas, and heavy industry.
3. Product Series
3300 XL 8 mm Proximity Transducer System (Reverse Mount Type)
This series is designed for precise non-contact measurement of shaft vibration and position in critical rotating machinery such as turbines, compressors, pumps, and motors.
4. Product Introduction
The 330105-02-12-20-05-00 is an 8 mm reverse mount proximity probe used for continuous monitoring of rotating machinery conditions.
It operates using eddy current sensing technology, allowing accurate measurement of distance changes between the probe tip and conductive metal shaft surfaces without physical contact.
The reverse mount design is optimized for compact mechanical structures where traditional axial installation is difficult or impossible.
This probe is typically used as part of a complete monitoring system including:
- Proximity probe
- Extension cable
- Proximitor signal conditioner
Together, these components form a stable vibration monitoring chain for predictive maintenance and machinery protection systems.
