Bently Nevada 330905-03-10-50-02-00 Proximity Probe Product Detailed Introduction
1. Product Introduction
The Bently Nevada 330905-03-10-50-02-00 is a 3300 XL 8 mm Proximity Probe designed for precise measurement of shaft vibration, radial displacement, and mechanical position changes in rotating equipment. It is widely used in machinery condition monitoring systems where accurate and continuous measurement of shaft movement is required.
This model uses advanced eddy current sensing technology. The probe creates an electromagnetic field between the sensing tip and the rotating shaft surface. Any change in the gap distance between the probe and the shaft generates a corresponding electrical signal, which is analyzed by the monitoring system to evaluate machine operating conditions.
The 330905-03-10-50-02-00 belongs to the 3300 XL 8 mm Proximity Probe Series. It is designed for industrial applications requiring high reliability, stable signal performance, and long-term operation under demanding working conditions.
This proximity probe is mainly installed on critical rotating machinery such as steam turbines, gas turbines, compressors, pumps, motors, and generators. It provides important information for equipment protection, fault diagnosis, and predictive maintenance.
The compact 8 mm sensing design allows installation in areas with limited space while maintaining excellent measurement accuracy and mechanical durability.

3. Product Structure and Working Principle
The 330905-03-10-50-02-00 proximity probe is composed of several key components, including the sensing tip, probe housing, threaded mounting section, internal coil assembly, and electrical connection interface.
The sensing tip is the main measurement element. During operation, it produces a high-frequency electromagnetic field directed toward the rotating shaft. When the shaft moves due to vibration or displacement, the distance between the shaft and probe changes.
The change in distance modifies the electromagnetic field strength. The probe system converts these changes into electrical signals that represent the actual shaft movement.
The measurement process is completely non-contact, which eliminates mechanical friction between the sensor and rotating components. This design improves reliability and allows continuous monitoring of machinery operating conditions.
A complete monitoring system usually includes:
- 3300 XL Proximity Probe
- Extension Cable
- Proximitor Sensor
- Monitoring Module
Together, these components provide a complete solution for vibration monitoring and machinery protection.
