Product Introduction
The Epro PR6480/041-000 Eddy Current Sensor is a high-precision, non-contact displacement and vibration measurement device engineered for industrial condition monitoring and machine protection applications. Part of the PR6480 series, this sensor provides accurate real-time monitoring of shaft displacement, vibration, and position in rotating machinery.
Using eddy current technology, the sensor generates an alternating electromagnetic field, inducing eddy currents in nearby conductive surfaces. The resulting response is measured to determine precise displacement or vibration. This allows engineers to monitor dynamic and static shaft movement without mechanical contact, reducing wear and improving system reliability.
The PR6480/041-000 is compatible with Epro signal converters (CON011, CON021, CON031), forming a complete monitoring solution for turbines, compressors, pumps, motors, and gearboxes. Its robust stainless steel housing ensures dependable operation in extreme industrial environments, including high temperature, oil exposure, and mechanical vibration.
It is widely used in API 670-compliant machinery protection systems, providing high accuracy and stability for critical monitoring applications in power generation, process industries, and heavy machinery.
