EPRO PR6423/002-000+CON021 Eddy Current Sensor – Proximitor Seismic System
When a critical rotating machine loses its vibration monitoring capability, the consequences are immediate and severe: undetected shaft displacement, catastrophic bearing failure, unplanned downtime, and in worst cases, complete turbine or compressor destruction. In high-stakes industrial environments — power generation, petrochemical processing, offshore platforms — a single failed proximity sensor can trigger a cascade of failures costing hundreds of thousands of dollars per hour. The EPRO PR6423/002-000+CON021 eddy current sensor system exists precisely to prevent this scenario, providing continuous, non-contact measurement of shaft position and vibration with the reliability that critical machinery demands.
The PR6423/002-000+CON021 is a complete proximity measurement system comprising the PR6423/002-000 eddy current probe paired with the CON021 signal conditioning extension cable. Within EPRO’s renowned PR6423 series — the industry benchmark for machine protection instrumentation — this configuration is engineered for medium-range displacement measurement in demanding environments. Trusted by OEMs and end-users across more than 100 countries, EPRO proximity systems are specified by major turbine manufacturers including GE, Siemens, MAN, and Solar Turbines, making this model one of the most globally deployed vibration sensing solutions in industrial automation.
