Product Introduction
The Epro PR6425/010-100 is a 16mm Eddy Current Sensor designed to deliver precise, reliable, and non-contact measurement of displacement, vibration, and position in industrial machinery. Part of Epro’s PR6425 series, this sensor is engineered for applications that demand high accuracy and stability in harsh industrial environments.
The sensor head detects changes in the distance to conductive targets using the eddy current principle, converting variations in impedance into proportional electrical signals. These signals can be used for real-time monitoring, feedback control, and predictive maintenance. The 16mm sensor head provides a practical balance between compact design and measurement accuracy, making it suitable for both tight installations and larger industrial equipment.
The PR6425/010-100 is capable of stable operation under temperature extremes, vibration, and electromagnetic interference, making it ideal for applications in power generation, turbines, compressors, heavy machinery, and industrial automation systems.
