Function and Working Principle
The CON021 + PR6423/010-100-CN operates based on the eddy current sensing principle. The probe generates an electromagnetic field that interacts with a conductive target surface such as a rotating shaft.
This allows:
Non-contact measurement of displacement and vibration
Detection of shaft position, eccentricity, and movement
High-speed response to dynamic changes
Stable operation in harsh industrial environments
Changes in the distance between the probe and the target are converted into electrical signals by the CON021 converter, enabling real-time monitoring and analysis.
