Where This Product Is Used
The EPRO PR6423/10R-030 CON021 eddy current sensor is deployed across critical rotating machinery and high-reliability industrial environments where non-contact displacement and vibration measurement is essential:
- Steam & Gas Turbines — shaft radial vibration monitoring per API 670 requirements
- Centrifugal Compressors — rotor dynamic displacement measurement in oil & gas processing trains
- Large Electric Motors & Generators — bearing journal orbit analysis and eccentricity detection
- Pumps & Fans — continuous shaft position monitoring in power generation and petrochemical plants
- Paper & Steel Mills — roll gap and position sensing in high-temperature, high-vibration environments
- Marine Propulsion Systems — shaft alignment verification and thrust position monitoring
- Nuclear & Thermal Power Plants — safety-critical machinery protection systems

Why Engineers Specify This Model
- Non-contact measurement — zero mechanical wear, ideal for continuous 24/7 machinery protection
- High frequency response — captures sub-synchronous, synchronous, and super-synchronous vibration components
- Immune to oil, steam, and contamination — robust in harsh process environments without signal degradation
- Direct drop-in compatibility with EPRO MMS 6000 / MMS 6350 and legacy Bently Nevada 3300 series monitoring systems
- 10 mm probe diameter — optimal balance between sensitivity and installation clearance in tight bearing housings
- CON021 connector — field-proven, vibration-resistant locking connector for reliable signal integrity
- Long cable run (3 m) — sufficient reach from bearing housing to junction box without signal loss

Application-Specific FAQ
Q: Is the PR6423/10R-030 CON021 compatible with Bently Nevada 3300 series monitors?
A: The EPRO PR6423 series uses the same eddy current principle and similar signal levels, but connector and driver compatibility must be verified. Contact us for a compatibility assessment.
Q: What shaft material is this probe calibrated for?
A: Standard factory calibration is for AISI 4140 steel. If your shaft is stainless steel, titanium, or another alloy, a recalibration factor must be applied. We can advise on correction coefficients.
Q: Can this sensor be used in ATEX Zone 1 hazardous areas?
A: Verify the ATEX/IECEx certification marking on the physical unit label. Not all PR6423 variants carry Ex certification. Confirm with us before installation in classified areas.
Q: What is the difference between the probe and the extension cable?
A: The PR6423 is the sensing probe (tip + integral cable). The PR6426 is a separate extension cable used when the probe cable alone cannot reach the driver. The 030 suffix on this model indicates the integral cable is 3 m.
Q: Do you provide calibration certificates?
A: Original OEM calibration documentation is provided where available. Third-party recalibration services can be arranged upon request.
