Product Introduction
The Epro PR6423/011-000 8mm Eddy Current Sensor is a precision-engineered industrial sensor designed for non-contact measurement of shaft displacement, vibration, and relative position in rotating machinery. As part of Epro’s renowned PR6423 series, this sensor offers high sensitivity, outstanding stability, and robust performance in harsh environments.
Specifically tailored for critical applications where continuous monitoring of machine conditions is essential, the PR6423/011-000 provides reliable feedback to prevent unplanned downtime. Built to handle high vibration, extreme temperatures, and electromagnetic interference, it is a trusted solution for industries such as power generation, oil & gas, petrochemical, and heavy machinery.
With its 8mm tip diameter, this sensor is ideal for medium-sized shaft monitoring, balancing the need for installation flexibility and precise signal output. When paired with matching extension cables and proximity measurement modules (e.g., CON011 or CON021), the PR6423/011-000 delivers a complete eddy current measurement system.
