Description
Product Description
The Emerson EPRO PR6423/011-100 is a precision 8 mm proximity probe designed for non-contact measurement of shaft movement in rotating machinery. It enables accurate monitoring of vibration, axial displacement, and shaft position, supporting machinery protection strategies in high-demand industrial environments.
As part of the PR6423 probe family, this model is optimized for integration with eddy current signal converters such as CON021, forming a complete measurement chain within MMS 6000 and AMS 6500 systems. Its mechanical design and material selection ensure stable operation under high temperature, oil exposure, and vibration conditions typically found in turbomachinery applications.
