Présentation du produit
The Epro PR6423/10R-131 is a non-contact eddy current displacement sensor designed to provide accurate and reliable measurements sur shaft vibration and axial displacement in critical rotating machinery. Belonging to the highly respected PR6423 series from Epro (now part sur Emerson), this model is frequently used in turbine generators, compressors, pumps, and other dynamic machinery where monitoring shaft behavior is essential for predictive maintenance and protection systems.
The sensor operates based on the eddy current principle, which allows it to detect changes in the distance between the sensor probe and the rotating target (typically the shaft) without physical contact. This ensures longevity, accuracy, and minimal interference in high-speed environments. With an 8mm tip diameter and a 10R configuration, the PR6423/10R-131 is optimized for industrial-grade use and can be paired with CON-series extension cables and CON0xx driver modules to form a complete displacement measurement system.
