Industrial Proximity Probe Technical Report (330104-16-21-10-01-00)

1. Product Overview

The model 330104-16-21-10-01-00 is an 8mm eddy current proximity probe used for precise measurement of shaft vibration, displacement, and axial position in rotating machinery.

It is a non-contact sensor designed to continuously monitor the gap between the probe tip and a conductive metallic surface, typically a rotating shaft.

This model belongs to a standardized configuration system where each suffix defines probe length, case length, cable assembly, connector type, and calibration options.

It is widely used in machinery protection and condition monitoring systems for real-time equipment health assessment.

2. Brand Information

Brand: Industrial rotating machinery condition monitoring instrumentation manufacturer

This product line is globally recognized in vibration monitoring systems and is widely applied in power generation, oil & gas, petrochemical, and marine industries.

3. Product Series

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

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

It is fully compatible with extension cables and proximitor modules within the same system architecture.

4. Product Introduction

The probe operates using eddy current sensing technology.

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

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

The system is designed for continuous operation in critical rotating machinery where early fault detection is essential.
