Product Description
Overview
The Emerson CON021 signal converter coupled with the PR6423/001-011-CN eddy current displacement sensor forms a precision monitoring system for critical rotating machinery. Designed for use in turbines, compressors, and pumps, this measurement chain provides non-contact detection of shaft displacement, radial vibration, and eccentricity, ensuring reliable operation of industrial equipment.
This system is part of the Emerson/AMS (formerly EPRO) product line and is engineered for high accuracy, durability, and seamless integration with advanced condition monitoring platforms such as TSI systems.

Applications
This measurement chain is widely used in TSI (Turbine Supervisory Instrumentation) and condition monitoring systems:
-
Radial Shaft Vibration: Tracks vibration in sleeve bearings to detect early faults
-
Axial Thrust Position: Measures longitudinal shaft movement to prevent internal contact damage
-
Phase Reference / Keyphasor: Provides rotational speed pulse and phase synchronization signals
Installation Note
Always ensure the sensor cable length matches the converter’s calibration. Using mismatched cable lengths can cause significant measurement errors and compromise system accuracy.
