EPRO PR6423/004-010 CON021 Eddy Current Sensor – PR6423 Series Non-Contact Vibration Probe
When a critical rotating machine — a steam turbine, compressor, or large pump — loses its shaft vibration monitoring capability, the consequences are immediate and severe. Without a functioning eddy current sensor, the protection system goes blind: operators cannot detect abnormal shaft displacement, rotor rub, or impending bearing failure. The result is unplanned downtime, catastrophic mechanical damage, and in the worst cases, safety incidents that shut down entire production lines. The EPRO PR6423/004-010 CON021 is the precision instrument that keeps those scenarios from ever occurring.
Within the PR6423 Series — EPRO’s flagship line of non-contact eddy current probes — the PR6423/004-010 is the 8mm diameter, 10mm cable-length variant paired with the CON021 extension cable assembly. This combination is engineered for direct integration with Bently Nevada 3300 and 3500 series monitoring systems, making it one of the most widely deployed shaft vibration sensors in global turbomachinery protection applications. EPRO (now part of Baker Hughes) sensors are trusted in power generation, oil & gas, petrochemical, and heavy manufacturing facilities across more than 100 countries.

Key Features & Benefits
- Non-Contact Measurement: Zero mechanical wear — the probe never touches the rotating shaft, ensuring indefinite service life under normal conditions.
- High Linearity: Delivers consistent, repeatable output across the full measurement range, critical for alarm and trip setpoint accuracy.
- CON021 Cable Integration: Factory-matched extension cable maintains system calibration without field re-calibration, reducing commissioning time.
- Drop-in Bently Nevada Compatibility: Electrically and mechanically compatible with Bently Nevada 3300/3500 monitor cards — no signal conditioning adapters required.
- Robust Construction: Stainless steel probe body and armored cable withstand harsh industrial environments including high humidity, vibration, and chemical exposure.
- Wide Temperature Range: Suitable for both ambient-temperature gearboxes and high-temperature steam turbine bearing housings.
Industry & Equipment Applications
- Power Generation: Steam turbines, gas turbines, hydro generators — shaft radial vibration and axial position monitoring.
- Oil & Gas: Centrifugal compressors, expanders, pipeline pumps — API 670 compliant machinery protection.
- Petrochemical & Refining: Reactor agitators, large blowers, critical process pumps.
- Marine & Offshore: Propulsion shaft monitoring, diesel generator sets.
- Heavy Manufacturing: Paper mill rolls, steel mill drives, large HVAC chillers.

Frequently Asked Questions
Q: Is the PR6423/004-010 CON021 a direct replacement for Bently Nevada 330104 series probes?
A: The PR6423/004-010 is an EPRO-branded probe designed for compatibility with Bently Nevada 3300/3500 monitor systems. Electrical compatibility is generally confirmed, but we recommend verifying gap voltage and sensitivity settings with your system integrator before installation.
Q: What is the difference between CON011, CON021, and CON031 cables?
A: These designations refer to different extension cable lengths and connector configurations within the EPRO PR6423 system. CON021 is the standard mid-length extension. Contact us with your installation drawing for exact cable selection guidance.
Q: Can this sensor be used with non-EPRO monitor systems?
A: Yes, with appropriate signal conditioning. The PR6423 outputs a standard DC voltage proportional to gap distance. Third-party monitors that accept –24 VDC powered proximity probe inputs can typically interface with this sensor.
Q: Do you provide ATEX/IECEx certification documentation?
A: Yes. Certification documents are available upon request for units supplied from certified stock. Please specify your hazardous area classification when inquiring.
Q: What is your minimum order quantity (MOQ)?
A: MOQ is 1 piece. We welcome both single-unit replacement orders and bulk procurement contracts.
