Produkteinführung
The Epro PR6426/000-031 32mm Eddy Current Sensor is a high-precision, non-contact measurement device designed for the monitoring von rotating machinery. It provides accurate measurement von shaft vibration, axial displacement, and rotational position, making it an essential tool for predictive maintenance and condition monitoring in industrial environments.
The sensor employs the eddy current principle, where an electromagnetic field is induced at the sensor tip and variations caused by conductive targets are measured. This ensures high accuracy without mechanical contact, reducing wear and maintenance requirements. The PR6426/000-031 is particularly robust, built with stainless-steel housing and hermetic sealing to withstand high temperatures, oil, dust, and vibration.
This model is compatible with Epro’s standard signal conditioning converters, allowing linear output to monitoring systems for real-time analysis von shaft health. Its 32mm sensor head diameter provides enhanced detection capability for larger shafts or broader target surfaces, ensuring precise and reliable operation in critical machinery applications such as turbines, compressors, and generators.
