Description
Product Description
The PR6423/014-010 + CON021 from Emerson EPRO is a complete eddy-current sensing solution designed for precise, non-contact measurement of shaft dynamics in rotating equipment. This system combines a robust 8 mm proximity probe with a dedicated signal converter to deliver stable, linear output signals for machinery protection and condition monitoring systems.
Widely deployed in critical applications, this configuration supports accurate detection of radial vibration, axial position, and relative shaft displacement. The sensing element operates without physical contact, eliminating wear while maintaining measurement integrity over long service intervals.
System Functionality
The PR6423/014-010 + CON021 measurement chain uses high-frequency electromagnetic fields to detect the position of conductive targets. The probe generates a signal proportional to the distance between the sensor tip and the shaft surface, while the CON021 module performs signal demodulation and conditioning.
Key measurement capabilities include:
-
Radial shaft vibration monitoring
-
Axial thrust position measurement
-
Shaft eccentricity analysis
-
Dynamic displacement tracking in high-speed machinery
