Industrial Proximity Probe System – Model 330903-00-02-10-12-05
1. Brand Positioning
This product belongs to a high-precision industrial vibration and shaft displacement monitoring category used in rotating machinery protection systems.
It is associated with Bently Nevada, a globally recognized provider of condition monitoring technologies for turbines, compressors, and critical rotating equipment.
2. Product Series
The model 330903-00-02-10-12-05 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 environments
- Integration into protection and monitoring systems
Typical system structure:
- Proximity probe
- Extension cable
- Signal conditioning module
3. Product Overview
This probe is a precision eddy current displacement sensor designed to measure the distance between a probe tip and a conductive rotating shaft.
It converts mechanical movement into a proportional electrical voltage signal, enabling real-time monitoring of vibration, axial movement, and radial displacement.
The configuration “00-02-10-12-05” represents a specific calibration and structural variant optimized for particular industrial conditions and installation requirements.
4. Working Principle
The system operates based on eddy current induction:
- High-frequency electromagnetic field generated at probe tip
- Conductive target induces eddy currents
- Impedance changes are detected
- Output voltage corresponds to displacement
Key benefits:
- No physical contact with rotating parts
- No mechanical wear or friction
- Stable long-term signal output
- High sensitivity to micro-displacement
