Function and Working Principle
The housing assembly serves as a protective interface for proximity probes.
Working Principle
- A 3300 XL proximity probe is installed inside the housing assembly.
- The probe is positioned close to the rotating shaft without physical contact.
- Changes in shaft movement are detected by the probe.
- Measurement signals are transmitted to the monitoring system.
- The housing ensures stable probe alignment and protects the probe from environmental hazards, mechanical damage, and contamination.
This design allows accurate, non-contact monitoring of rotating machinery.
