EPRO PR6423/010-140 CON011 Eddy Current Proximity Sensor – PR6423 Series
When a critical rotating machine loses its vibration and displacement monitoring capability, the consequences are immediate and severe: undetected shaft imbalance, bearing wear, or rotor rub can escalate within minutes into catastrophic equipment failure, unplanned downtime, and six-figure repair costs. The EPRO PR6423/010-140 CON011 eddy current proximity sensor system is the precision instrument that stands between normal operation and disaster — continuously measuring shaft displacement and vibration with micron-level accuracy, 24 hours a day, without physical contact.
Within the PR6423 Series, the PR6423/010-140 variant is engineered for a 10 mm probe tip diameter with a 140 mm armored extension cable, paired with the CON011 proximitor/signal conditioner. This combination delivers a calibrated output range optimized for heavy-duty turbomachinery, compressors, and generator sets. The PR6423 Series is globally recognized as a direct functional equivalent to Bently Nevada 3300 XL series probes, making it one of the most widely deployed eddy current sensor families in industrial plants across petrochemical, power generation, and marine industries worldwide.

Frequently Asked Questions
Q: Is the EPRO PR6423/010-140 CON011 a direct replacement for Bently Nevada 3300 XL probes?
A: Yes. The PR6423/010-140 with CON011 proximitor is fully compatible with Bently Nevada 3300 XL monitoring systems and produces the same -24V output signal and 200 mV/mil sensitivity, requiring no rack reconfiguration.
Q: What is the difference between CON011 and CON021?
A: The CON011 is the standard proximitor for the PR6423 series, optimized for general-purpose turbomachinery monitoring. The CON021 offers extended temperature range and is preferred for high-heat applications above 85°C ambient.
Q: Can this sensor be used in hazardous (Ex) areas?
A: The PR6423 series is available in ATEX/IECEx certified variants. Please confirm your area classification (Zone 1/Zone 2) when submitting your inquiry so we can verify the correct certification suffix.
Q: What is the lead time for the PR6423/010-140 CON011?
A: In-stock units ship within 1–3 business days. For larger quantities or special configurations, lead time is typically 2–4 weeks. Contact us for real-time stock confirmation.
Q: Do you provide calibration certificates?
A: Yes. Factory calibration documentation is available upon request. Third-party calibration services can also be arranged for critical applications.
