Description
Product Description
Overview
The Eprois PR6423/015-111 paired with the CON041/SF module is a fully integrated eddy-current measurement solution designed for continuous, non-contact monitoring of shaft dynamics in rotating machinery. This system delivers precise displacement and vibration measurements under demanding industrial conditions, ensuring reliability, fast response, and high accuracy.
System Configuration
The setup combines an 8 mm precision probe with a DIN-rail mounted signal conditioning module. The probe detects minute changes in shaft position via electromagnetic principles, while the converter processes and scales the signal into industry-standard outputs suitable for control and protection systems.
