Typical Applications

This configuration is specifically suited for deep-access installations where physical stability and standard cable reach are required:

• Internal Bearing Monitoring: The 4.0-inch body facilitates measurement through thick housing walls or internal support structures.

• Axial Position Sensing: Tracking thrust bearing movement in high-pressure centrifugal compressors to ensure rotor safety.

• Radial Vibration Analysis: Monitoring shaft-to-bearing clearance in large induction motors and utility turbines.

• Keyphasor Reference: Providing a once-per-revolution pulse for speed measurement and vibration phase analysis.
