Description
Product Description
The PR6423/010-020-CN + CON021 measurement system from Emerson EPRO is a precision eddy-current solution developed for continuous, non-contact monitoring of rotating machinery. This configuration integrates an 8 mm proximity probe with a dedicated signal conditioner, forming a complete measurement chain for displacement and vibration analysis.
The probe detects shaft movement without physical contact, while the CON021 unit processes and linearizes the signal into a stable output suitable for integration with machinery protection systems such as MMS 6000 and AMS 6500. This combination is commonly implemented in applications where accuracy, durability, and resistance to industrial contamination are critical.
Measurement Principle and Functionality
The PR6423/010-020-CN + CON021 system operates on the eddy-current principle, enabling precise detection of metallic shaft position and dynamic motion. It is suitable for:
-
Radial shaft vibration monitoring
-
Axial displacement (thrust position) measurement
-
Shaft eccentricity detection
-
Relative movement analysis in high-speed rotating equipment
The preamplifier ensures consistent signal conditioning, minimizing noise and maintaining measurement linearity across the operating range.
