5. Product Introduction
This probe operates based on the eddy current principle. A high-frequency electromagnetic field is generated at the probe tip. When a conductive surface approaches, eddy currents are induced, and the resulting signal variation is converted into a proportional displacement output.
The system is designed for continuous online monitoring rather than intermittent measurement.
It is commonly installed close to rotating shafts where real-time vibration and position tracking is required.
The “02-05” configuration typically reflects specific cable length and assembly configuration variations for industrial deployment.
