CON021 + PR6423/010-130 by EPRO | Shaft & Vibration Monitoring

EPRO CON021 + PR6423/010‑130 Eddy Current Sensor System – Product Description

Overview

The Emerson EPRO CON021 paired with PR6423/010‑130 is a high-precision eddy-current sensor system designed for critical rotating machinery applications. This non-contact sensor system accurately measures shaft displacement, radial and axial positions, eccentricity, and speed/keyphasor signals. Moreover, the radiation-resistant PR6423 probe makes it ideal for nuclear power plant monitoring and other extreme industrial environments. Its robust design and API 670 compliance ensure reliable performance in turbines, compressors, pumps, fans, and motors.
