Industrial Proximity Probe Technical Report (330105-02-12-05-02)
1. Product Overview
The model 330105-02-12-05-02 is an 8mm eddy current proximity probe used for precise monitoring of shaft vibration, radial displacement, and axial position in rotating machinery systems.
It is a non-contact sensor designed to continuously measure the distance between the probe tip and a conductive rotating shaft surface.
The model belongs to a standardized proximity transducer architecture widely used in machinery protection and predictive maintenance systems.
The configuration code defines probe length, case design, cable type, connector style, and system calibration options.
2. Brand Information
Brand: Industrial rotating machinery condition monitoring instrumentation manufacturer
This product line is widely applied in:
- Vibration monitoring systems
- Predictive maintenance platforms
- Rotating equipment protection systems
- Heavy industrial condition monitoring
3. Product Series
This model belongs to the 3300 XL 8mm Proximity Probe Series.
The series is designed for:
- High accuracy non-contact displacement measurement
- Long-term operational stability
- Harsh industrial environment resistance (oil, dust, vibration, temperature)
- Compatibility with standard proximity transducer systems
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 metal shaft moves within this field, eddy currents are induced on the surface of the shaft.
These changes in the electromagnetic field are converted into a proportional analog voltage signal.
This signal is used for:
- Shaft vibration measurement
- Radial displacement monitoring
- Axial position detection
It enables continuous real-time monitoring of rotating machinery condition.
