5. Product Description
The 330103-07-12-10-02-00 is designed for continuous monitoring of rotating shafts, providing real-time displacement data.
It operates using eddy current technology, where an electromagnetic field interacts with a conductive target, producing a voltage signal proportional to displacement.
The 07-12 configuration offers a balanced design that allows installation in medium-depth mounting locations without requiring excessive space.
Its rugged design ensures stable operation in environments with:
- Oil contamination
- Dust exposure
- Mechanical vibration
The probe is suitable for long-term operation with consistent accuracy.
6. Applications
Typical industrial applications include:
- Steam turbines
- Gas turbines
- Compressors
- Pumps
- Electric motors
- Gear systems
Measurement functions:
- Radial vibration monitoring
- Axial displacement measurement
- Shaft position tracking
- Speed reference (Keyphasor use)
7. Product Advantages
High Measurement Accuracy
Delivers stable and repeatable measurements for critical systems.
Non-contact Operation
No mechanical wear, increasing lifespan and reliability.
Compact Mechanical Design
Suitable for installations with limited mounting space.
Strong Environmental Resistance
Reliable performance under oil, dust, and vibration conditions.
System Compatibility
Fully compatible with standard 3300 XL monitoring systems.
