Bently Nevada 330904-00-10-10-01-05 Proximity Probe Product Introduction, Technical Parameters and Application Guide
1. Product Introduction
The Bently Nevada 330904-00-10-10-01-05 is a high-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 applied in industrial machinery condition monitoring, shaft vibration measurement, displacement detection, and equipment protection systems.
The probe adopts advanced eddy current sensing technology to perform accurate non-contact measurement between the probe tip and the rotating shaft. The sensor detects changes in the distance between the probe and the conductive shaft surface, converting shaft movement into an electrical output signal proportional to the measured displacement.
The 330904-00-10-10-01-05 is designed for applications requiring extended installation flexibility, reliable measurement performance, and stable operation under demanding industrial conditions. It is commonly used on critical rotating equipment including steam turbines, gas turbines, compressors, generators, motors, and industrial pumps.
This proximity probe provides continuous monitoring of shaft vibration, radial displacement, and axial movement. By delivering accurate operating information, it helps maintenance personnel identify mechanical problems at an early stage, improve equipment availability, and reduce the risk of unexpected failures.
The 8 mm sensing element provides a good balance between measurement accuracy and installation convenience. The compact structure allows use in limited spaces while maintaining excellent signal stability and long-term reliability.

5. Product Structure and Working Principle
The 330904-00-10-10-01-05 consists of a sensing tip, metal probe housing, integrated cable assembly, and electrical connection interface.
The probe works based on eddy current sensing technology.
When the probe is powered, it generates a high-frequency electromagnetic field around the sensing area. When the rotating shaft moves closer or farther away from the probe, the electromagnetic field changes.
The sensor detects this change and converts it into an electrical signal proportional to the shaft displacement.
The monitoring system analyzes this signal to evaluate the mechanical condition of the equipment.
The non-contact measurement design provides several advantages:
- No physical contact with rotating parts.
- Reduced mechanical wear.
- Accurate measurement during high-speed operation.
- Stable output signal.
- Long operating life.
