The Emerson PR6423/010-010 is a non-contact eddy current proximity sensor (probe) designed for precise measurement of shaft vibration, displacement, and position in rotating machinery. This sensor operates on the eddy current principle, enabling accurate monitoring of conductive target surfaces without physical contact. It is widely used as part of machinery protection and condition monitoring systems in industrial environments.
The PR6423 series is commonly paired with signal converters such as CON021 or CON041 modules, forming a complete measurement chain for turbomachinery applications.
The PR6423/010-010 is typically used in critical rotating equipment such as turbines, compressors, pumps, and gearboxes, where continuous vibration monitoring is essential for operational safety and predictive maintenance.
