Bently Nevada 330904-00-10-05-02-05 Proximity Probe Product Introduction, Technical Parameters and Application Guide
1. Product Introduction
The Bently Nevada 330904-00-10-05-02-05 is a high-performance proximity probe designed for continuous monitoring of rotating machinery operating conditions. It belongs to the 3300 XL 8 mm Proximity Transducer System Series, which is widely applied in industrial machinery protection, shaft vibration monitoring, displacement measurement, and predictive maintenance systems.
This proximity probe adopts eddy current sensing technology to achieve accurate non-contact measurement between the probe tip and the rotating shaft. The sensor detects the variation of the distance between the probe and the conductive shaft surface and converts the mechanical displacement into a proportional electrical signal.
The 330904-00-10-05-02-05 is developed for applications where accurate measurement, stable signal transmission, and long-term operating reliability are essential. It is commonly used on critical rotating equipment such as turbines, compressors, generators, motors, and pumps.
The probe continuously monitors shaft vibration, radial displacement, and mechanical movement conditions. By providing real-time condition information, it helps operators identify abnormal operating situations, prevent unexpected failures, and improve maintenance efficiency.
The compact 8 mm sensing structure allows installation in restricted spaces while maintaining excellent measurement performance. Its rugged industrial design provides reliable operation under environments with continuous vibration, temperature changes, and mechanical stress.

5. Product Structure and Working Principle
The 330904-00-10-05-02-05 consists of a sensing tip, protective metal body, integrated cable assembly, and electrical connection interface.
The product operates using eddy current sensing technology.
When the probe is energized, a high-frequency electromagnetic field is generated around the sensing tip. When the rotating shaft moves, the gap distance between the shaft surface and the probe changes.
The change in distance affects the electromagnetic field strength. The probe converts this variation into an electrical signal proportional to shaft movement.
The monitoring system receives and processes the signal to evaluate machine operating conditions.
The non-contact measurement design provides:
- No physical contact with rotating components.
- Reduced mechanical wear.
- Improved measurement stability.
- Suitable operation at high rotational speeds.
- Extended service life.
