Industrial Proximity Probe System – Model 330902-04-48-10-02-05
1. Brand & Product Positioning
This product belongs to a high-precision industrial vibration and shaft displacement monitoring category used in rotating machinery protection systems.
It is commonly associated with Bently Nevada, which is widely used in power generation, oil & gas, and heavy industrial applications.
2. Product Series
The model 330902-04-48-10-02-05 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 machinery protection systems
Typical system structure:
- Proximity probe
- Extension cable
- Proximitor 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 surface such as a shaft.
It converts mechanical movement into a stable analog voltage signal, enabling real-time monitoring of vibration, axial position, and radial displacement.
The “04-48-10” configuration represents a specific calibration and mechanical variant optimized for certain installation and measurement conditions within the same product family.
4. Working Principle
The system operates based on eddy current induction:
- High-frequency electromagnetic field is generated at the probe tip
- Conductive target induces eddy currents
- Impedance variation is detected
- Output voltage is proportional to displacement
Key benefits of this principle:
- No physical contact with shaft
- No mechanical wear
- Stable long-term signal performance
- High sensitivity to micro-displacement changes
