Industrial Proximity Probe Technical Report (330105-02-12-05-02-05-BR)
1. Product Overview
The model 330105-02-12-05-02-05-BR is an 8mm eddy current proximity probe designed for high-precision monitoring of shaft vibration, radial displacement, and axial position in rotating machinery systems.
It is a non-contact sensor that measures the distance between the probe tip and a conductive rotating shaft in real time, enabling continuous machinery condition monitoring and protection functions.
The suffix “-BR” typically indicates a regional or configuration variant, often associated with Brazil-specific packaging, certification, or supply coding in industrial distribution systems.
This probe is part of a modular transducer system widely used in critical rotating equipment monitoring.
2. Brand Information
Brand: Industrial rotating machinery condition monitoring instrumentation manufacturer
This product line is widely used in:
- Power generation plants
- Oil & gas processing facilities
- Petrochemical industries
- Marine propulsion systems
- Heavy rotating machinery industries
3. Product Series
This model belongs to the 3300 XL 8mm Proximity Probe Series.
Key characteristics of this series include:
- High precision non-contact displacement sensing
- Long-term operational stability
- Resistance to oil, dust, vibration, and extreme temperature
- Compatibility with standard proximity monitoring systems
- Compliance with industrial reliability requirements (API-style machinery protection applications)
Reference system architecture: probe + extension cable + proximitor sensor.
4. Product Introduction
The probe uses 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 its surface.
These changes in electromagnetic field strength are converted into a proportional analog voltage signal.
This signal is used to measure:
- Shaft vibration amplitude
- Radial displacement
- Axial movement
It enables continuous real-time monitoring for predictive maintenance and machinery protection systems.
