Bently Nevada 330904-00-10-05-02-00 Proximity Probe Product Introduction, Technical Parameters and Application Guide
1. Product Introduction
The Bently Nevada 330904-00-10-05-02-00 is a precision 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 used for industrial shaft vibration measurement, displacement monitoring, and machinery protection applications.
The probe uses eddy current sensing technology to provide accurate non-contact measurement between the probe tip and the rotating shaft. By detecting changes in the gap between the probe and the conductive shaft surface, the sensor converts shaft movement into a proportional electrical signal that can be analyzed by monitoring systems.
The 330904-00-10-05-02-00 is designed for critical rotating equipment that requires high measurement stability, accurate displacement detection, and long-term operating reliability. It is commonly installed on steam turbines, gas turbines, compressors, generators, motors, and industrial pumps.
The probe continuously monitors shaft vibration and displacement conditions, helping operators identify abnormal mechanical behavior at an early stage. It provides important information for predictive maintenance, machine protection, and equipment reliability improvement.
The compact 8 mm sensing element provides excellent installation flexibility and allows the probe to be used in applications where mounting space is limited. The durable construction ensures stable operation under industrial conditions involving vibration, temperature variation, and continuous mechanical stress.

5. Product Structure and Working Principle
The 330904-00-10-05-02-00 consists of a sensing tip, protective probe housing, integrated cable assembly, and electrical connection interface.
The product operates based on eddy current sensing technology.
When the probe receives electrical power, it generates a high-frequency electromagnetic field near the sensing tip. When the rotating shaft moves, the distance between the shaft surface and the probe changes.
The change in gap distance affects the electromagnetic field strength. The probe converts this variation into an electrical output signal proportional to the shaft displacement.
The monitoring system processes this signal to evaluate machine condition and identify possible mechanical issues.
The non-contact measurement design provides:
- No direct contact with rotating components.
- Reduced mechanical wear.
- Reliable operation at high rotational speeds.
- Stable measurement accuracy.
- Long service life.
