Product Overview
In industrial condition monitoring systems, precise and stable measurement of shaft displacement and vibration is critical for maintaining the safety and efficiency of rotating machinery. The Epro CON021 + PR6424/010-120 Eddy Current Sensor is engineered to deliver high-accuracy, non-contact measurement using advanced eddy current technology.
This system integrates a 16 mm probe (PR6424/010-120) with a signal converter (CON021), enabling accurate monitoring of shaft position, vibration, and dynamic behavior in turbines, compressors, and other high-value industrial equipment.

Function and Working Principle
The CON021 + PR6424/010-120 operates based on the eddy current sensing principle. The probe generates a high-frequency 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 dynamic movement
High-speed response to mechanical changes
Stable operation in harsh industrial environments
The variation in the probe-to-target gap is converted into electrical signals by the CON021 converter, enabling precise real-time monitoring and analysis.
