Function and Working Principle
The housing assembly acts as a protective enclosure and mounting support for proximity probes.
Working Principle
- Install a 3300 XL proximity probe inside the housing.
- Position the probe near the rotating shaft without physical contact.
- Shaft vibration, displacement, and rotor position are detected by the probe.
- Signals are transmitted to monitoring and protection systems.
- The housing maintains stable probe alignment and protects the probe and cabling from environmental and mechanical stresses.
This ensures continuous and accurate machinery condition monitoring.
