5. Product Description
This proximity probe is designed for continuous online monitoring of rotating shafts. It detects displacement changes by generating an electromagnetic field and measuring variations caused by conductive targets.
The 06-25 configuration indicates a longer case length compared to similar models, making it suitable for installations where additional mounting depth is required.
Its rugged mechanical structure ensures stable performance under harsh operating conditions, including oil exposure and high vibration.
The probe is typically integrated with an extension cable and a proximitor sensor to form a complete monitoring system.
6. Applications
Typical applications include:
- Steam turbines
- Gas turbines
- Compressors
- Pumps
- Electric motors
- Gearboxes
Measurement capabilities:
- Radial shaft vibration
- Axial displacement
- Shaft position monitoring
- Speed reference (when used as Keyphasor)
7. Product Advantages
High Precision
Capable of detecting very small displacement changes with stable output.
Non-contact Operation
No physical contact with the shaft, reducing wear and maintenance.
Extended Installation Flexibility
Longer case length allows installation in deeper or restricted mounting locations.
Strong Environmental Resistance
Operates reliably in oil, dust, and vibration-heavy environments.
Stable Signal Output
Maintains consistent measurement under varying operating conditions.
