Bently Nevada 330904-00-24-10-02-05 Proximity Probe Product Introduction, Technical Parameters and Application Guide
1. Product Introduction
The Bently Nevada 330904-00-24-10-02-05 is a precision proximity probe designed for continuous condition monitoring of critical rotating machinery. It belongs to the 3300 XL 8 mm Proximity Transducer System Series, which is widely used for shaft vibration measurement, displacement monitoring, and machinery protection applications.
This proximity probe uses 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 gap between the probe and the conductive shaft surface and converts this mechanical movement into an electrical signal proportional to displacement.
The 330904-00-24-10-02-05 is designed for industrial environments where high measurement accuracy, long-term stability, and reliable operation are required. It is commonly installed on high-value rotating equipment such as turbines, compressors, generators, motors, and industrial pumps.
The probe provides continuous monitoring of shaft vibration, radial movement, and axial displacement. By collecting real-time operating information, it helps identify mechanical problems before they become serious failures, supporting predictive maintenance and improving equipment availability.
The 8 mm sensing element provides a compact installation size while maintaining excellent measurement performance. The probe structure is suitable for applications where installation flexibility, signal reliability, and long service life are important factors.

5. Product Structure and Working Principle
The 330904-00-24-10-02-05 consists of a sensing tip, protective probe housing, 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 created around the sensing tip. As the rotating shaft moves, the distance between the shaft surface and the probe changes.
The change in gap distance modifies the electromagnetic field strength. The probe converts this variation into an electrical signal that represents the shaft displacement.
The monitoring system processes the signal to evaluate machine operating conditions and identify possible mechanical abnormalities.
The non-contact measurement method provides:
- No physical contact with rotating components.
- Reduced mechanical wear.
- Accurate measurement at high operating speeds.
- Stable output performance.
- Long operational service life.
