EPRO PR6426/000-110 CON021 Eddy Current Displacement Sensor

The EPRO PR6426/000-110 CON021 is a robust eddy current displacement sensor designed for non-contact monitoring of shaft displacement and position in critical rotating machinery. This configuration features a threadless sensor body, making it suitable for applications that require installation via a dedicated mounting structure rather than conventional threaded mounting arrangements.

The sensor is supplied with an integrated mounting plate measuring 80 mm × 40 mm, providing a secure and stable installation platform for machinery protection and condition monitoring systems. The configuration is designed without armored cable protection, offering increased flexibility and reduced overall weight in installations where additional mechanical shielding is not required.

The PR6426/000-110 CON021 is also configured without an adaptor plug, simplifying the probe assembly while maintaining reliable measurement performance. It includes a 5-meter cable for convenient connection to signal converters and monitoring equipment located away from the measurement point. The cable is terminated with a LEMO connector, ensuring secure electrical connectivity, excellent signal integrity, and seamless integration with compatible EPRO monitoring systems.

Engineered for continuous operation in demanding industrial environments, the PR6426/000-110 CON021 provides precise, non-contact measurement of shaft displacement, position, and rotor movement. It is widely applied in steam turbines, gas turbines, compressors, pumps, and other critical rotating assets where accurate machinery condition monitoring is essential for predictive maintenance, equipment protection, and operational reliability.
