Function and Working Principle
The housing assembly ensures accurate probe operation by:
- Providing stable mechanical alignment with the rotating shaft.
- Maintaining a consistent probe-to-shaft gap, crucial for precise eddy-current measurements.
- Protecting the probe and cabling from dust, oil, moisture, and mechanical impact.
- Allowing easy installation, adjustment, and maintenance without full machinery disassembly.
Although the housing itself does not perform measurements, it is vital for reliable and precise probe readings.
