Product Introduction
The Epro PR6425/010-110 is a 16mm Eddy Current Sensor designed for high-precision, non-contact measurement of displacement, vibration, and position in industrial machinery. As part of Epro’s PR6425 series, this sensor delivers reliable performance and exceptional accuracy for demanding applications.
The sensor operates on the eddy current principle, where variations in distance between the sensor tip and a conductive target generate changes in electrical impedance. These changes are converted into proportional electrical signals, allowing for real-time monitoring, process control, and predictive maintenance. The 16mm sensor head provides a practical balance between compact design and robust measurement capability, making it suitable for installation in both tight and standard industrial environments.
Engineered for industrial conditions, the PR6425/010-110 operates reliably in high vibration, fluctuating temperatures, and electromagnetic interference, making it suitable for applications in power generation, turbines, compressors, industrial automation, and heavy machinery.
