Shaft Vibration & Displacement Monitoring Solution – EPRO PR6424/012-000 CON011 | Bently Nevada Compatible Series
Where This Product Is Used
The EPRO PR6424/012-000 CON011 eddy current proximity sensor is engineered for continuous, non-contact measurement of shaft radial vibration, axial position, and differential expansion in rotating machinery. Typical deployment environments include:
- Steam & Gas Turbines – Rotor eccentricity and shaft orbit monitoring per API 670
- Centrifugal Compressors – Radial bearing clearance and thrust position measurement
- Pumps & Fans – Continuous proximity sensing for predictive maintenance programs
- Gearboxes – Gear mesh frequency analysis and shaft runout detection
- Electric Motors (>500 kW) – Air-gap monitoring and rotor dynamic analysis
- Petrochemical & Refinery Plants – SIL-rated machinery protection systems

Application-Specific FAQ
Q: Is the PR6424/012-000 CON011 a direct replacement for the Bently Nevada 330780-50-00?
A: Yes, in most installations. Both use an 8 mm tip, 200 mV/mil sensitivity, and -24 VDC supply. Verify connector compatibility and cable length before installation.
Q: What target material is this sensor calibrated for?
A: Factory calibration is performed on AISI 4140 steel. For Inconel, titanium, or other alloys, a field re-calibration with the actual target material is recommended.
Q: Can this sensor be used in a hazardous area (ATEX/IECEx)?
A: The standard PR6424/012-000 is not ATEX-rated. For Zone 1/2 applications, specify the EPRO PR6424/012-100 ATEX variant or contact us for alternatives.
Q: What is the maximum shaft speed this sensor can monitor?
A: The 10 kHz frequency response supports shaft speeds up to approximately 600,000 RPM for once-per-revolution events, well beyond typical turbomachinery requirements.
Q: Do you supply calibration certificates?
A: Yes. Factory calibration data and certificates of conformance are available. Request at time of order or email [email protected].
