Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or equivalents for the PR9376/010-011. Compatibility depends on your driver/oscillator system and installation geometry — consult the selection guide below before substituting.
| Model | Manufacturer | Compatibility Notes |
|---|---|---|
| PR9376/010-011 | EMERSON / Bently Nevada | OEM original — direct fit |
| PR9376/010-021 | EMERSON / Bently Nevada | Extended cable variant; same probe head |
| 3300 XL 8mm Probe | Bently Nevada | Newer platform; requires 3300 driver — verify driver compatibility |
| PR6423/010-030 | EPRO (EMERSON) | EPRO-series equivalent; widely used in turbine monitoring |
| CON021/916-000 | EPRO | Paired driver for EPRO PR6423 series |

| CS-1 / CS-3 | Wilcoxon / Amphenol | General-purpose proximity; confirm API 670 compliance |
⚠ Important: Proximity sensors must be used with their matched driver/oscillator. Mixing unmatched probe-driver pairs will result in incorrect output scaling and potential system faults.
Why Choose the Original Model
- API 670 Compliance: The PR9376/010-011 is designed to meet API 670 machinery protection standards, critical for turbomachinery applications.
- Proven Field Reliability: Decades of deployment in power generation, oil & gas, and petrochemical plants worldwide.
- Seamless System Integration: Plug-and-play compatibility with existing Bently Nevada 3500/3300 monitoring systems — no recalibration required.
- Factory Calibration: Each unit is factory-calibrated and traceable, reducing commissioning time.
- OEM Warranty & Support: Full EMERSON after-sales support and documentation availability.
Typical Applications
- Shaft radial vibration monitoring on steam and gas turbines
- Axial position (thrust) measurement on compressors and pumps
- Differential expansion monitoring in power plant turbines
- Eccentricity and rotor runout measurement
- Keyphasor® reference signal generation (with appropriate driver)
- Rotating machinery protection systems per API 670
System Compatibility
The PR9376/010-011 probe is designed for use with the following driver/oscillator and monitoring systems:
- Bently Nevada 3500 Series — Machinery Protection System (MPS)
- Bently Nevada 3300 Series — Monitoring modules (verify probe-driver matching)
- EPRO MMS 6000 / MMS 6350 — With appropriate EPRO driver
- Custom DCS/PLC Integration — Via signal conditioner; 4–20 mA or voltage output conversion may be required
Always confirm the probe-driver system scale factor (mV/mil or mV/mm) matches your monitor configuration before installation.
Selection Guide
Use the following decision framework to select the correct proximity sensor for your application:
- Step 1 — Identify your driver system: Bently Nevada 3500/3300, EPRO MMS, or third-party? The probe must match the driver brand and series.
- Step 2 — Confirm cable length: The suffix code in PR9376/010-011 indicates cable/extension length. Measure your installation distance carefully.
- Step 3 — Verify target material: Eddy-current sensors are sensitive to target conductivity. Confirm your shaft material (carbon steel, stainless, Inconel, etc.) and apply the correct scale factor.
- Step 4 — Check gap range: Ensure the nominal air gap at installation falls within the linear range of the sensor (typically 0.25–2.25 mm for 5 mm probes, 0.5–2.5 mm for 8 mm probes).
- Step 5 — Confirm API 670 requirement: If your plant requires API 670 compliance, only use OEM or certified equivalent parts with traceable calibration documentation.
- Step 6 — Replacement vs. upgrade: If upgrading to a newer platform (e.g., 3300 XL), consult EMERSON engineering for system-level compatibility and recalibration requirements.

Replacement & Compatibility FAQ
Q: Can I replace PR9376/010-011 with a PR6423 series EPRO probe?
A: Potentially yes, but only if your monitoring system supports EPRO probes and the driver is changed accordingly. The two series use different drivers and are not interchangeable without system-level changes.
Q: What does the suffix “/010-011” mean?
A: The suffix encodes cable length and connector configuration. “/010” typically refers to the extension cable length (1.0 m), and “-011” identifies the connector/termination type. Always match the suffix to your installation requirements.
Q: Is the PR9376/010-011 compatible with Bently Nevada 3500/40M monitors?
A: Yes, when used with the correct driver module. Verify the scale factor setting in the 3500/40M matches the probe-driver system output (7.87 V/mm or 200 mV/mil).
Q: Can I use this sensor on an aluminum shaft?
A: Yes, but the scale factor will differ from a steel shaft. Aluminum targets require a correction factor — consult the Bently Nevada probe/driver calibration documentation for your specific target material.
Q: Do you provide calibration certificates?
A: Yes. Calibration certificates and material traceability documents are available upon request for all OEM units.
Q: What is the lead time for out-of-stock units?
A: Typically 2–4 weeks for factory orders. Contact us for current stock availability before placing an urgent order.
