Function and Working Principle
This housing assembly plays a mechanical and environmental support role for proximity probes:
- Provides precise mechanical alignment between probe and rotating shaft.
- Maintains a stable probe-to-target gap, essential for accurate eddy-current measurement.
- Protects probe and cable from oil, dust, moisture, and mechanical impact.
- Reduces installation errors by ensuring fixed probe positioning geometry.
- Enables external access for maintenance and replacement without dismantling machinery.
It does not generate signals itself, but ensures the probe operates under correct physical conditions.
