Product Overview
In industrial condition monitoring systems, accurate measurement of shaft displacement and vibration is essential for ensuring the reliability and safety of rotating machinery. The Epro CON021 + PR6424/001-030 Eddy Current Sensor is designed to deliver high-precision, non-contact measurement using eddy current technology.
This system combines a 16 mm probe (PR6424/001-030) with a signal converter (CON021), enabling stable monitoring of shaft position, vibration, and dynamic movement. It is widely used in turbomachinery and industrial rotating equipment where consistent and accurate measurement is required.

Function and Working Principle
The CON021 + PR6424/001-030 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 and eccentricity
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.
