EPRO PR6423/10R-141 CON031 Eddy Current Sensor – PR6423 Series
When a critical rotating machine — a gas turbine, compressor, or high-speed pump — loses its shaft vibration monitoring capability, the consequences are immediate and severe: undetected rotor imbalance, bearing wear, or catastrophic mechanical failure can shut down an entire production line within minutes. Without a reliable non-contact displacement sensor at the heart of the protection system, operators are flying blind. The EPRO PR6423/10R-141 CON031 eddy current sensor eliminates that risk, delivering continuous, real-time shaft position and vibration data that keeps your machinery — and your operation — running safely.
Within the EPRO PR6423 series, the PR6423/10R-141 CON031 occupies a precision mid-range position, engineered for 10 mm probe tip diameter applications requiring a 141 mm cable extension and CON031 connector interface. EPRO (now part of Baker Hughes / Bently Nevada ecosystem) is recognized globally as a benchmark supplier for turbomachinery protection instrumentation, with PR6423-series sensors deployed across power generation, oil & gas, petrochemical, and heavy industrial facilities on every continent.

Key Features & Benefits
- Non-Contact Measurement: Zero mechanical wear — the sensor never touches the rotating shaft, ensuring indefinite service life under normal operating conditions.
- High-Frequency Response: Capable of capturing high-speed vibration events that contact-type sensors miss, critical for turbomachinery protection.
- Robust Industrial Construction: Designed to withstand harsh environments including oil mist, high temperatures, and electromagnetic interference common in industrial plants.
- Direct System Compatibility: Engineered to interface with EPRO and Bently Nevada monitoring systems without signal conditioning adapters.
- Precise Shaft Centerline Tracking: Enables both dynamic vibration measurement and static shaft position (gap) monitoring in a single probe.
- CON031 Connector Standard: Ensures secure, vibration-resistant field connections with industry-standard mating connectors.
Industry & Equipment Applications
- Power Generation: Steam turbines, gas turbines, hydro generators — shaft vibration and axial position monitoring.
- Oil & Gas: Centrifugal compressors, expanders, pipeline pumps — API 670 compliant machinery protection.
- Petrochemical & Refining: Reactor agitators, process compressors, critical rotating equipment.
- Marine & Offshore: Propulsion turbines and auxiliary machinery on vessels and platforms.
- Heavy Industry: Steel mill drives, paper mill rolls, large industrial fans and blowers.
- Water & Wastewater: High-speed pump protection systems.
