Function and Working Principle
The housing assembly ensures accurate and reliable probe operation by:
- Providing stable mechanical alignment with the rotating shaft.
- Maintaining a consistent probe-to-shaft gap, which is essential for precise eddy-current measurements.
- Protecting the probe and cabling from dust, oil, moisture, and mechanical damage.
- Allowing easy installation, adjustment, and maintenance without full machinery disassembly.
While the housing itself does not perform measurements, it is critical for the accuracy and reliability of 3300 XL proximity probe readings.
