Key Benefits
Contact-free sensing eliminates mechanical wear
High signal fidelity and measurement consistency
Designed for endurance in industrial environments
Provides actionable data for predictive maintenance
Operates effectively across a wide temperature span

Operating Principle
This probe uses eddy current technology to establish an electromagnetic field at the tip. Changes in the gap between the probe and a conductive target modulate the return signal, allowing connected electronics to compute precise position and movement data.
Typical Use Cases

The proximity probe is used in:
Shaft vibrational analysis
Monitoring radial and axial displacement
Rotary equipment clearance measurement
Early detection of machinery abnormalities
Integration with plant monitoring systems
It is ideal for turbines, pumps, compressors, and heavy-duty rotating assets.
Installation and Setup

Use standard M10 threaded fittings for secure mounting
Confirm the target surface is conductive and properly aligned
Adjust the probe-to-target gap according to system calibration needs
Follow manufacturer recommendations for cable routing and strain relief
