Product Description

Overview

The Emerson PR6423/010-010 probe combined with the CON021 signal converter provides precise, non-contact eddy-current measurement for industrial machinery. This system captures micro-scale shaft vibration, axial displacement, and eccentricity with high accuracy, ensuring early detection of mechanical faults. Moreover, its robust design allows reliable operation in high-temperature and high-pressure environments, making it suitable for turbines, compressors, pumps, and motors.

The 10 mm probe tip and 10-meter integral cable enable flexible installations where longer sensor runs are required. In addition, the CON021 module converts raw signals into standard outputs, simplifying integration with PLCs or DCS platforms, including Allen-Bradley ControlLogix and Bently Nevada 3500 monitoring systems.
