EPRO PR6423/000-131 Product Description
Product Overview
EPRO PR6423/000-131 is a high-precision 8 mm eddy current displacement sensor developed by EPRO (Emerson Process Management) for continuous condition monitoring of critical rotating machinery. As a member of the EPRO PR6423 series, EPRO PR6423/000-131 is designed for non-contact measurement of shaft vibration, axial displacement, radial displacement, rotor position, eccentricity, and rotational speed. It is widely used in machinery protection systems where high accuracy, fast response, and long-term measurement stability are required.
The EPRO PR6423/000-131 uses advanced eddy current measurement technology, generating a high-frequency electromagnetic field between the probe tip and the conductive shaft surface. Changes in the measurement gap are converted into proportional electrical signals, allowing precise monitoring of dynamic shaft movement without mechanical contact. This non-contact design eliminates wear caused by friction and enables reliable operation in high-speed rotating equipment exposed to vibration, oil contamination, and temperature fluctuations.
As a core sensing element in EPRO MMS 3000, MMS 6000, and modern Emerson machinery health monitoring solutions, EPRO PR6423/000-131 is typically combined with signal converters such as CON021, CON041, or equivalent monitoring modules to create a complete vibration protection measurement chain. The model suffix 000-131 represents a specific factory configuration with an 8 mm probe, 8 m cable length, and open cable termination, making it suitable for customized installation in industrial machinery monitoring systems.
