The PR6423/000-031-CN sensor generates a high-frequency electromagnetic field near the conductive target surface. As the rotating shaft moves within the sensing range, eddy currents are induced on the target surface, causing changes in the electromagnetic field characteristics. These variations are converted into precise displacement signals.
The CON021 converter processes the raw sensor signals and converts them into stable standardized outputs suitable for machinery monitoring and protection systems.
This enables:
Continuous non-contact shaft monitoring
High-precision vibration measurement
Reliable signal conditioning and transmission
Real-time machine condition analysis
