Industrial Proximity Probe Technical Report (330104-15-25-05-02-05)

1. Product Overview

The model 330104-15-25-05-02-05 is an 8mm eddy current proximity probe used for precise measurement of shaft vibration and axial displacement in rotating machinery.

It is designed as a non-contact sensing device that continuously measures the gap between the probe tip and a conductive metallic surface, typically a rotating shaft.

The configuration code defines the probe mechanical structure, case length, cable length, and connector type, making it suitable for standardized industrial monitoring systems.

This model is widely applied in critical rotating equipment where continuous condition monitoring and early fault detection are essential.

2. Product Series

This product belongs to the 3300 XL 8mm Proximity Probe System Series.

This series is known for high accuracy, long-term stability, and strong resistance to harsh industrial environments such as high temperature, vibration, oil mist, and dust exposure.

3. Brand Information

Brand: Global industrial machinery condition monitoring instrumentation manufacturer

This product line is widely used in vibration monitoring systems, predictive maintenance solutions, and rotating equipment protection across power generation, petrochemical, and heavy industry sectors.

4. Product Introduction

The probe operates using eddy current sensing technology, where a high-frequency electromagnetic field is generated at the probe tip.

When a conductive target such as a rotating shaft moves relative to the probe, eddy currents are induced in the surface, altering the electromagnetic field.

These changes are converted into a proportional analog voltage signal, which is used by monitoring systems to analyze vibration, displacement, and shaft position in real time.

It is designed for continuous industrial operation and long service life in harsh environments.
