Emerson Epro CON021 + PR6424/000-100 Eddy Current Sensor System

Description

The Emerson Epro PR6424/000-100 sensor paired with the CON021 signal converter forms a high-performance eddy current measurement system. It’s designed for non-contact monitoring of shaft displacement, vibration, and rotational speed in critical rotating machinery such as turbines, compressors, and pumps. This combo is widely used in predictive maintenance and machine protection applications across power generation, oil & gas, and heavy industry.
