² Description
The EPRO PR6423/001-010-CN CON021 is a precision eddy current displacement sensor engineered for non-contact monitoring of critical rotating machinery in industrial environments. Designed with an 8 mm probe tip diameter, the sensor provides highly accurate measurement of shaft displacement, vibration, eccentricity, and position, making it suitable for advanced machinery protection and condition monitoring systems.
This model features an M10 × 1 threaded housing with a 35 mm thread length, ensuring secure installation and reliable mechanical stability in applications involving turbines, compressors, pumps, motors, and other rotating equipment. The sensor is supplied without armored cable protection, offering a flexible and lightweight configuration for installations where additional mechanical shielding is not required.
The PR6423/001-010-CN CON021 is equipped with a 5.0-meter integrated cable, allowing convenient connection to signal converters and monitoring systems located away from the measurement point. The cable is terminated with a LEMO connector, providing secure electrical connectivity, excellent signal integrity, and compatibility with EPRO monitoring solutions.
Built for continuous operation in demanding industrial conditions, the PR6423/001-010-CN CON021 delivers stable and repeatable measurement performance, helping operators detect shaft movement abnormalities at an early stage, improve equipment reliability, and support predictive maintenance programs across power generation, oil and gas, petrochemical, and process industries.
