Rotating Machinery Vibration Monitoring Solution — EPRO CON021 PR6423/011-000 | Eddy Current Sensor
Where This Product Is Used
The EPRO CON021 PR6423/011-000 Eddy Current Sensor is a non-contact displacement and vibration transducer engineered for continuous condition monitoring of rotating and reciprocating machinery. Typical deployment environments include:
- Steam & Gas Turbines — shaft radial vibration, axial position, and differential expansion measurement
- Centrifugal Compressors — rotor orbit analysis and bearing clearance monitoring in oil & gas trains
- Pumps & Blowers — early-warning vibration trending in process-critical rotating equipment
- Gearboxes & Fans — shaft eccentricity and runout detection in power generation and petrochemical plants
- Marine Propulsion Systems — continuous shaft monitoring in confined, high-vibration environments
- Test Rigs & OEM Machinery — precision displacement feedback in R&D and acceptance testing
This sensor is a direct component of the EPRO PR6423 series, fully compatible with Emerson’s machinery protection and condition monitoring systems including the CSI 6500 and Bently Nevada 3500 platform (with appropriate signal conditioning).

Application-Specific FAQ
Q: Is the PR6423/011-000 compatible with Bently Nevada 3500 systems?
A: The PR6423 series uses the same eddy current principle and signal range as Bently Nevada probes, but is an EPRO-branded product. Compatibility with 3500 I/O modules depends on the driver output range. Contact us for a compatibility assessment before ordering.
Q: What target material is required for accurate measurement?
A: The probe is calibrated for AISI 4140 steel. For stainless steel or other alloy shafts, a material correction factor must be applied. EPRO provides calibration curves for common shaft materials.
Q: Can this probe be used in ATEX Zone 1 hazardous areas?
A: The probe itself is passive; ATEX certification is determined by the paired CON021 driver module. Confirm the driver’s ATEX category with your safety engineer before installation.
Q: What is the difference between PR6423/011-000 and PR6423/010-000?
A: The suffix denotes cable length and connector configuration. The /011-000 variant features a 1.0 m integral cable. Always verify the full part number against your system drawing before ordering.
Q: Do you offer calibration or repair services?
A: Konmask supplies new and surplus units. For calibration or repair, we recommend engaging an Emerson-authorized service center. We can provide referrals upon request.
