Function and Working Principle
The housing assembly serves as a protective enclosure and precision mounting structure for proximity probes.
Working Principle
- A 3300 XL proximity probe is installed inside the housing.
- The probe is positioned close to the rotating shaft without physical contact.
- Shaft movement, vibration, and displacement are detected by the probe.
- Signals are transmitted to monitoring and protection systems.
- The housing maintains stable alignment and protects the probe and cable from mechanical and environmental stress.
This ensures continuous, accurate, and reliable machinery monitoring.
