u Overview
The EPRO PR6423/002-130 CON021 is a high-performance eddy current displacement sensor designed for precise, non-contact monitoring of critical rotating machinery. Featuring an 8 mm probe tip diameter, the sensor provides accurate measurement of shaft displacement, vibration, eccentricity, and position, making it well suited for advanced machinery protection and condition monitoring systems.
This configuration is equipped with an M10 × 1 threaded housing and a 45 mm thread length, ensuring secure mounting and dependable mechanical stability in a wide range of industrial applications. The sensor is supplied without armored cable protection, offering a lightweight and flexible installation solution where additional mechanical shielding is not required.
The PR6423/002-130 CON021 includes a 5.0-meter integrated cable, allowing convenient installation and connection to signal converters or monitoring equipment. The cable is terminated with an open cable end, providing maximum flexibility for field wiring and custom integration into existing control, monitoring, and machinery protection systems.
Designed for continuous operation in demanding environments, the PR6423/002-130 CON021 is commonly used in steam turbines, gas turbines, compressors, pumps, fans, and other rotating assets where accurate shaft motion monitoring is essential. Its non-contact sensing technology delivers stable, high-resolution measurement data that supports early fault detection, predictive maintenance programs, improved equipment reliability, and reduced unplanned downtime.
