Industrial Proximity Probe Technical Report (330105-02-12)
1. Product Overview
The model 330105-02-12 is an 8mm eddy current proximity probe used for precise measurement of shaft vibration, radial displacement, and axial position in rotating machinery.
It is a non-contact sensing device designed to continuously monitor the distance between the probe tip and a conductive rotating shaft surface.
This model is part of a standardized proximity transducer system widely used in machinery protection and condition monitoring applications.
The configuration suffix “02-12” typically represents probe mechanical length, case style, cable configuration, and installation variant within the 3300 XL architecture.
2. Brand Information
Brand: Industrial rotating machinery condition monitoring instrumentation manufacturer
This product line is widely used in predictive maintenance and vibration monitoring systems across power generation, oil & gas, petrochemical, marine, and heavy industrial sectors.
3. Product Series
This model belongs to the 3300 XL 8mm Proximity Probe System Series.
Key characteristics of the series include:
- High precision non-contact displacement measurement
- Long-term stability in harsh environments
- Compatibility with extension cables and proximitor sensors
- Compliance with industrial machinery monitoring standards (API-style applications)
4. Product Introduction
The probe works based on eddy current electromagnetic induction technology.
A high-frequency electromagnetic field is generated at the probe tip. When a conductive metal shaft moves within this field, eddy currents are induced on its surface.
These changes are converted into a proportional analog voltage signal.
This signal is used to measure:
- Shaft vibration amplitude
- Radial displacement
- Axial position
It is widely used for continuous real-time monitoring of rotating machinery condition.
