The PR6423 series 8 mm eddy current sensor is designed for non‑contact measurement of shaft displacement, 

vibration, eccentricity, and axial or radial movement in rotating machinery. It uses eddy current sensing to detect 

small changes in distance or position of ferromagnetic targets (e.g. shafts), making it ideal for critical turbomachinery 

such as turbines, compressors, pumps, or fans, where precise, reliable monitoring of shaft behavior is essential.
