Bently Nevada 330105-02-12-15-12-CN Full Technical Overview
1. Product Title
330105-02-12-15-12-CN 3300 XL 8 mm Reverse Mount Proximity Probe
2. Brand
This product belongs to a globally recognized industrial condition monitoring technology brand widely used in vibration monitoring, shaft displacement measurement, and rotating machinery 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 330105-02-12-15-12-CN is an 8 mm reverse mount proximity probe used for continuous monitoring of rotating machinery condition.
It works based on eddy current sensing technology, which measures the distance variation between the probe tip and conductive metal shaft surfaces without physical contact.
The reverse mount structure is used in compact machinery layouts where axial installation space is limited or conventional mounting cannot be applied.
The “CN” suffix generally refers to a configuration or compliance version intended for specific regional or regulatory requirements, while maintaining standard 3300 XL electrical performance.
This probe is normally used as part of a full 3-component system:
- Proximity probe
- Extension cable
- Proximitor signal conditioner
Together, they form a complete vibration monitoring chain used in industrial protection and predictive maintenance systems.

- Conductive shaft surface induces eddy currents
- Distance change alters electromagnetic response
- Output voltage corresponds to vibration/displacement level
This allows real-time condition monitoring of rotating machinery.
9. System Composition
A complete monitoring system includes:
- 8 mm reverse mount proximity probe (this model)
- Coaxial extension cable (1.5 m typical CN configuration)
- Proximitor signal conditioning module
