Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or equivalents for the PR9268/017-100. Always verify electrical and mechanical compatibility before substitution:
- Emerson PR9268/011-100 – Shorter cable variant; same probe body, different cable length
- Emerson PR9268/020-100 – Longer cable variant for extended reach installations
- Emerson PR6423/000-030 – Alternative proximity probe series, widely used in API 670 systems
- Bently Nevada 330101-00-06-10-02-00 – Industry-standard 3300 XL 8mm proximity transducer; functionally equivalent in many API 670 setups
- Bently Nevada 330130-040-00-00 – 3300 XL 11mm probe; check gap range and sensitivity before substitution
- EPRO PR9268/017-100 – Legacy EPRO part number (now Emerson); identical product
Note: Replacement suitability depends on gap range, sensitivity (V/mm), driver compatibility, and installation geometry. Contact Konmask for application-specific guidance.
Why Choose the Original Model
- API 670 Certified – Meets the most stringent machinery protection standards for turbomachinery
- Proven Field Reliability – Widely deployed in power generation, oil & gas, and petrochemical plants globally
- System Integrity – Designed to work seamlessly with Emerson/EPRO driver electronics and monitoring systems (e.g., MMS 6000, CSI 6500)
- Calibrated Sensitivity – Factory-calibrated output ensures accurate vibration amplitude readings without field recalibration
- Long Service Life – Robust stainless steel construction with IP67 protection for harsh industrial environments
Typical Applications
- Steam and gas turbine shaft vibration monitoring
- Centrifugal compressor radial and axial displacement measurement
- Pump and motor bearing condition monitoring
- Gearbox and fan shaft speed and position sensing
- Power generation (nuclear, thermal, hydro) machinery protection systems
- Oil & gas upstream / downstream rotating equipment
System Compatibility
The PR9268/017-100 probe is designed for use within the Emerson / EPRO PR9268 proximity transducer system. Typical system configurations include:
- Driver / Signal Conditioner: PR9268/200-xxx series (must be ordered separately)
- Extension Cable: PR9268/300-xxx series (length-dependent)
- Monitoring System: Emerson CSI 6500, MMS 6000, or third-party API 670-compliant monitors
- DCS Integration: Compatible with 4–20 mA output modules for DCS/SCADA integration via signal conditioners
Selection Guide
Use the following criteria to confirm the PR9268/017-100 is the correct model for your application:
- Cable Length: Confirm the probe-to-driver distance. The /017 suffix indicates ~1 m probe cable; add extension cable as needed.
- Target Material: Eddy-current probes are optimized for specific shaft materials (steel, stainless steel, Inconel). Verify sensitivity factor.
- Gap Range: Confirm the linear operating range matches your installation gap (typically 0.25–2.25 mm for standard 8 mm probes).
- Thread Size: Verify probe body thread (M8 or M10) matches your existing bracket or housing.
- Driver Compatibility: Ensure the paired driver/conditioner is from the PR9268/200 series or a verified compatible unit.
- Certification Requirements: For API 670 systems, confirm the complete probe-driver-cable system is certified as a matched set.

Replacement & Compatibility FAQ
Q: Can I replace PR9268/017-100 with a Bently Nevada 330101 series probe?
A: Functionally similar in many API 670 systems, but the driver electronics are not interchangeable. You must replace the complete probe-driver-cable system as a matched set.
Q: What does the “/017” suffix mean?
A: The suffix indicates the probe cable length variant (~1.7 m total or ~1 m probe cable depending on configuration). Always verify with the full system datasheet.
Q: Is the PR9268/017-100 the same as the EPRO PR9268/017-100?
A: Yes. Emerson acquired EPRO; the part number and product are identical. Both designations refer to the same sensor.
Q: Do you offer calibration certificates?
A: Yes. Calibration certificates and certificates of conformance are available upon request for OEM units.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days. For large quantities or special configurations, contact us for lead time confirmation.
