EPRO PR6423/10R-111 Eddy Current Proximity Sensor System – PR6423 Series Proximity Transducer
In critical rotating machinery — turbines, compressors, pumps, and generators — an undetected shaft displacement or vibration anomaly can escalate from a minor imbalance to a catastrophic mechanical failure within seconds. Without a reliable, continuously operating proximity measurement system, plant operators are flying blind. The EPRO PR6423/10R-111 Eddy Current Sensor System eliminates that blind spot, delivering real-time, non-contact shaft position and vibration data that forms the backbone of any serious condition monitoring strategy.
The PR6423/10R-111 is a 10 mm diameter eddy current probe within EPRO’s industry-standard PR6423 series — one of the most widely deployed proximity transducer families in global turbomachinery protection systems. Engineered to interface seamlessly with Bently Nevada 3300 and EPRO MMS6000/C6000 monitoring platforms, this sensor system is the preferred choice for OEMs, EPC contractors, and plant maintenance engineers who demand measurement accuracy, long-term stability, and proven field reliability across oil & gas, power generation, and heavy industrial environments.

Key Features & Benefits
- Non-Contact Measurement: Zero mechanical wear — the probe never touches the target shaft, ensuring indefinite service life under continuous operation.
- High Frequency Response: Capable of capturing high-speed vibration events and sub-millisecond displacement changes critical for turbomachinery protection.
- ATEX / IECEx Certified: Intrinsically safe design approved for use in Zone 0/1 hazardous areas — essential for offshore platforms and petrochemical plants.
- System-Matched Accuracy: Calibrated as a complete system (probe + extension cable + conditioner) to guarantee linearity and sensitivity across the full measurement range.
- Plug-and-Play Compatibility: Direct drop-in replacement for existing PR6423 installations; no recalibration of the monitoring rack required when replacing like-for-like.
- Robust Construction: Stainless steel probe body with hermetically sealed tip withstands aggressive lubricants, steam, and high-pressure environments.
- Long-Term Stability: Minimal drift over years of continuous operation — a key requirement for API 670-compliant machinery protection systems.
Industry & Equipment Applications
- Oil & Gas: Centrifugal compressors, gas turbines, LNG expanders, pipeline pumping stations
- Power Generation: Steam turbines, hydro generators, gas turbine-generators, boiler feed pumps
- Petrochemical & Refining: Reactor agitators, cracked gas compressors, process pumps
- Marine & Offshore: Propulsion shafts, thruster systems, diesel generator sets
- Heavy Industry: Paper mill rolls, steel mill drives, large induction motors
- Measurement Functions: Radial shaft vibration, axial thrust position, differential expansion, eccentricity, speed/phase reference (keyphasor)
