Bently Nevada 330904-00-25-10-01-00 Proximity Probe Product Introduction, Technical Parameters and Application Guide
1. Product Introduction
The Bently Nevada 330904-00-25-10-01-00 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 in industrial applications requiring accurate shaft vibration measurement, displacement monitoring, and machinery protection.
The probe uses eddy current sensing technology to perform non-contact measurement between the probe tip and the rotating shaft. Through electromagnetic field variation detection, the sensor accurately measures the change in distance between the probe and the conductive shaft surface and converts the mechanical displacement into an electrical output signal.
The 330904-00-25-10-01-00 is designed for applications where stable measurement performance, reliable signal transmission, and long operating life are required. It is commonly used for monitoring critical rotating equipment such as steam turbines, gas turbines, compressors, generators, motors, and industrial pumps.
The probe provides continuous information about shaft vibration, radial movement, and axial displacement. This allows operators and maintenance personnel to evaluate machine health, identify abnormal operating conditions, and perform maintenance before serious equipment damage occurs.
The 8 mm sensing element provides a compact structure with excellent measurement capability. The probe can be installed in areas where space is limited while maintaining high accuracy, stable output, and reliable operation under industrial environments.

5. Product Structure and Working Principle
The 330904-00-25-10-01-00 consists of a sensing tip, protective metal probe body, integrated cable assembly, and electrical connection interface.
The probe operates using eddy current sensing technology.
When electrical power is supplied, the sensing tip generates a high-frequency electromagnetic field. The rotating shaft changes its position relative to the probe during operation, causing the gap distance to vary.
The electromagnetic field changes according to the shaft movement. The probe converts these changes into an electrical signal proportional to the displacement distance.
The monitoring system receives the signal and analyzes the data to determine equipment operating conditions.
The non-contact sensing method provides:
- No direct contact with rotating components.
- Reduced mechanical wear.
- Accurate measurement at high rotational speeds.
- Stable signal output.
- Long operational service life.
