Product Introduction
The Epro PR6425/005-010 is a 16mm Eddy Current Sensor designed for precision measurement of displacement, vibration, and position in industrial machinery. This sensor is part of Epro’s PR6425 series, providing accurate non-contact measurement with high linearity and stability.
The sensor operates based on the eddy current principle, where variations in proximity between the sensor tip and a conductive target cause changes in electrical impedance. These changes are converted into proportional electrical signals suitable for control systems, diagnostics, and condition monitoring.
The PR6425/005-010 is optimized for industrial environments with vibration, electromagnetic interference, and temperature fluctuations, making it suitable for power generation, turbine monitoring, heavy machinery, and industrial automation. Its robust stainless steel construction ensures durability, while the 16mm diameter provides a balance between compact size and high measurement accuracy.
