Industrial Proximity Probe Technical Report (330105-02-12-02-05-00)
1. Product Overview
The model 330105-02-12-02-05-00 is an 8mm eddy current proximity probe designed for precise measurement of shaft vibration, radial displacement, and axial position in rotating machinery systems.
It is a non-contact sensor that continuously monitors the distance between the probe tip and a conductive rotating shaft surface, enabling real-time condition monitoring and machinery protection.
The configuration code defines probe mechanical length, case structure, cable assembly type, connector specification, and factory calibration settings.
This model is widely used in industrial predictive maintenance systems where stable, high-accuracy measurement is required under harsh operating conditions.
2. Brand Information
Brand: Industrial rotating machinery condition monitoring instrumentation manufacturer
This product line is widely applied in vibration monitoring, machinery diagnostics, and rotating equipment protection 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.
The series is engineered for:
- High precision non-contact displacement measurement
- Long-term operational stability
- Resistance to vibration, oil contamination, dust, and temperature variation
- Compatibility with industrial machinery protection systems
4. Product Introduction
The probe operates using eddy current electromagnetic induction technology.
A high-frequency electromagnetic field is generated at the probe tip. When a conductive shaft moves within this field, eddy currents are induced on the surface of the metal shaft.
These changes modify the electromagnetic field strength, which is converted into a proportional analog voltage signal.
This signal is used for:
- Shaft vibration measurement
- Radial displacement monitoring
- Axial position detection
It is widely used in continuous monitoring of rotating machinery for early fault detection.
