Epro PR6423/011-010 8mm Eddy Current Sensor

The Epro PR6423/011-010 is a non-contact, proximity-type eddy current displacement sensor designed for accurate and reliable measurement of the distance between a sensor and a conductive target surface. Built with precision and durability, this model is widely used in critical industrial monitoring applications such as vibration, axial displacement, and rotational speed measurement in turbomachinery.

With an 8 mm tip diameter, this sensor delivers excellent linearity, temperature stability, and noise immunity. It is designed for integration with the Epro CON0xx series converter modules, typically in condition monitoring and protection systems like those found in rotating equipment, including turbines, compressors, pumps, and motors. It offers superior performance under extreme industrial conditions such as high vibration, oil mist, or temperature fluctuations.
