Function and Working Principle
The housing assembly acts as a protective enclosure and precise alignment platform 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 contact.
- Shaft vibration, displacement, and rotor movement are detected by the probe.
- Signals are transmitted to monitoring and protection systems.
- The housing maintains stable alignment and protection against environmental and mechanical stress.
This ensures continuous and accurate machinery condition monitoring.
