Bently Nevada 330905-02-08-70-01-00 Proximity Probe Product Overview
1. Product Introduction
Bently Nevada 330905-02-08-70-01-00 is a high-performance 3300 XL 8 mm Proximity Probe designed for industrial condition monitoring and rotating machinery protection applications. It is part of the well-known Bently Nevada 3300 XL series, which is widely used for vibration measurement, shaft position monitoring, and machinery protection in critical rotating equipment.
This proximity probe is mainly installed together with an extension cable and a proximity sensor system to measure the relative movement between a rotating shaft and the machine housing. The probe works based on eddy current technology, providing accurate, stable, and continuous measurement signals for monitoring shaft vibration, radial displacement, axial position, and other mechanical operating conditions.
The 330905-02-08-70-01-00 model belongs to the 3300 XL 8 mm proximity probe family. It features a compact structure, high reliability, excellent environmental resistance, and long service life, making it suitable for demanding industrial environments such as power generation, petrochemical, oil and gas, marine, and heavy manufacturing industries.
The probe is designed for use with Bently Nevada 3300 XL Proximity Transducer Systems and is commonly paired with compatible extension cables and Proximitor sensors to form a complete monitoring channel.

3. Product Structure and Function
The 330905-02-08-70-01-00 proximity probe consists mainly of a sensing tip, probe body, threaded mounting section, and electrical connection interface.
The sensing tip generates an electromagnetic field around the shaft surface. When the shaft moves, the distance between the shaft and probe changes, causing variations in the electromagnetic field. These changes are converted into electrical signals that represent shaft displacement.
The system provides real-time monitoring of machinery operating conditions and helps operators identify abnormal conditions such as:
- Excessive vibration
- Shaft misalignment
- Rotor imbalance
- Mechanical looseness
- Bearing problems
- Thrust movement
- Rotor position changes
This makes it an essential component in predictive maintenance systems for critical rotating equipment.
