Industrial Proximity Probe System – Model 330902-36-89-05-01
1. Brand Positioning
This product belongs to a high-precision industrial vibration and displacement monitoring category used in rotating machinery protection systems.
It is widely associated with Bently Nevada, a globally recognized technology provider in condition monitoring, shaft vibration measurement, and predictive maintenance systems.
2. Product Series
The model 330902-36-89-05-01 is part of the 3300 XL 8mm Proximity Probe Series.
This series is designed for:
- Non-contact eddy current displacement measurement
- Continuous shaft vibration monitoring
- Harsh industrial operating environments
- Integration into machinery protection and control systems
Typical system configuration includes:
- Proximity probe
- Extension cable
- Signal conditioning driver (Proximitor type)
3. Product Overview
This probe is a precision eddy current displacement sensor used to measure the distance between a probe tip and a conductive rotating shaft.
It converts mechanical displacement into a stable electrical signal, allowing real-time monitoring of vibration, axial position, and radial movement.
The “36-89-05” configuration represents a specific mechanical and calibration variant within the same probe family, optimized for certain installation requirements and monitoring conditions.
The “01” suffix typically indicates a finalized production configuration or revision version.
4. Working Principle
The system operates using eddy current technology:
- A high-frequency electromagnetic field is generated at the probe tip
- A conductive surface (shaft) induces eddy currents
- Changes in impedance are detected by the system
- Output voltage is proportional to displacement
Key advantages:
- No physical contact with rotating parts
- No mechanical wear or friction
- High stability over long-term operation
- Excellent sensitivity to micro-vibrations
