System Compatibility
The PR9376/010-011 sensor is designed to operate as part of a complete eddy-current measurement chain. Ensure the following system components are matched:
- Driver/Oscillator: EPRO PR9268/xxx series (specify cable length and range)
- Extension Cable: EPRO PR9376/xxx extension cables (total cable length must match driver calibration)
- Monitoring Rack: EPRO MMS 6000 / MMS 3000, or Bently Nevada 3500 series (with appropriate I/O module)
- Target Gap: Calibrated gap per OEM datasheet (typically 1.0 mm nominal for 0–2 mm range)
Selection Guide
Use the following criteria to confirm the PR9376/010-011 is the correct sensor for your application:
- ✅ Gap range required: 0–2 mm linear range
- ✅ Cable length: 1.0 m sensor cable (total system cable length determined by extension cable)
- ✅ Target material: Steel or Inconel shaft
- ✅ Driver compatibility: EPRO PR9268 series driver
- ✅ Environment: Operating temperature within -35°C to +120°C
- ✅ Certification: CE / ATEX required for hazardous area installations

Replacement & Compatibility FAQ
Q: Can I use the PR9376/010-011 with a Bently Nevada 3500 rack?
A: Yes, with the appropriate interface module and driver. The output signal (voltage vs. gap) is compatible, but driver calibration must match. Consult our team for system-level verification.
Q: What is the difference between PR9376/010-010 and PR9376/010-011?
A: The last suffix typically denotes cable length or connector variant. The /010-011 has a 1.0 m cable. Verify with the OEM datasheet or contact us for clarification.
Q: Is a Bently Nevada 330101 a direct drop-in replacement?
A: Functionally similar, but mechanical dimensions and connector types differ. A qualified engineer must verify fit, gap, and driver compatibility before substitution in a live system.
Q: Do you supply calibration certificates?
A: Yes, calibration certificates are available for OEM new units. For surplus stock, functional test reports are provided upon request.
Q: Can you source other EPRO PR9376 variants?
A: Yes. We stock and source multiple PR9376 variants. Contact us with your full part number and we will confirm availability and pricing.
