Industrial Proximity Probe Technical Report (330104-16-21-05-01-RU)

1. Product Overview

The model 330104-16-21-05-01-RU is an 8mm eddy current proximity probe designed for high-precision monitoring of shaft vibration and displacement in rotating machinery systems.

It is a non-contact sensor used to measure the gap between the probe tip and a conductive rotating shaft, providing continuous real-time condition data.

The suffix “RU” typically indicates a regional or compliance-specific configuration variant used for particular market or certification requirements.

This probe is widely used in industrial machinery protection systems where reliability and continuous monitoring are critical.

2. Brand Information

Brand: Industrial rotating machinery condition monitoring instrumentation manufacturer

This product line is widely used in vibration monitoring, predictive maintenance systems, and rotating equipment protection across heavy industries such as power generation, oil & gas, petrochemical, and marine sectors.

3. Product Series

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

This series is engineered for high stability, strong signal accuracy, and excellent resistance to harsh industrial environments including high temperature, vibration, oil contamination, and dust exposure.

4. Product Introduction

The probe operates based on eddy current electromagnetic induction technology.

A high-frequency electromagnetic field is generated at the probe tip. When a conductive shaft surface moves relative to the probe, eddy currents are induced, altering the electromagnetic field strength.

These changes are converted into a proportional analog voltage signal used for measuring vibration, displacement, and shaft position in real time.

It is designed for continuous operation in mission-critical industrial environments.
