Compatible Replacement & Equivalent Models
When the OEM part is unavailable or lead times are unacceptable, the following models are commonly evaluated as replacements. Always verify electrical and mechanical compatibility before substitution:
| Part Number | Brand | Length | Compatibility Notes |
|---|---|---|---|
| 330190-080-00-05 | Bently Nevada | 80 in | Same series, shorter length — verify gap voltage |
| 330190-050-00-05 | Bently Nevada | 50 in | Same series, shorter length — verify gap voltage |
| 330190-200-00-05 | Bently Nevada | 200 in | Same series, longer length — verify system calibration |
| 3300 XL Extension Cable | Bently Nevada | Various | Upgraded 3300 XL series — check Proximitor compatibility |
| EX-series Extension Cable | Third-party OEM | Custom | Must match impedance, connector, and temperature rating |
⚠ Important: Extension cable length directly affects the system’s gap voltage calibration. Substituting a different length requires recalibration of the Proximitor sensor. Always consult the Bently Nevada System 1 calibration documentation.
Why Choose the Original Model
- Factory-calibrated system match: The 330190-130-00-05 is factory-matched to 3300 Series probes and Proximitor sensors — no field recalibration required when replacing like-for-like.
- Signal integrity: Precision coaxial construction minimizes capacitance variation, preserving the eddy-current field and measurement accuracy.
- Harsh-environment durability: Rated for wide temperature extremes and resistant to oils, coolants, and industrial chemicals common in rotating machinery environments.
- API 670 compliance: Ensures compatibility with machinery protection systems governed by API 670 standards for turbines, compressors, and pumps.
- Reduced commissioning risk: OEM parts eliminate compatibility unknowns during planned maintenance outages where downtime cost is high.
Typical Applications
- Steam and gas turbine shaft radial vibration monitoring
- Centrifugal compressor rotor position and vibration measurement
- Pump and motor bearing proximity sensing
- Gearbox and expander machinery protection systems
- Petrochemical, LNG, and power generation plant rotating equipment
- Offshore platform critical machinery monitoring
System Compatibility
The 330190-130-00-05 extension cable is designed for use within the complete Bently Nevada 3300 Series Proximity Transducer System, which consists of three matched components:
- Proximity Probe — e.g., 330101, 330103, 330104 series
- Extension Cable — 330190-130-00-05 (this part)
- Proximitor® Sensor — e.g., 330180, 330185 series
All three components must be from the same calibrated system family. Mixing components from different series (e.g., 3300 XL vs. standard 3300) without recalibration will result in measurement errors and may trigger false machinery protection trips.
Selection Guide
Use the following criteria to confirm the 330190-130-00-05 is the correct part for your application:
| Selection Criterion | Requirement | This Model |
|---|---|---|
| System Series | Bently Nevada 3300 | ✅ Compatible |
| Required Cable Length | 130 inches (3.3 m) | ✅ Exact match |
| Connector Standard | MIL-spec coaxial | ✅ Included |
| Operating Temperature | Up to 120°C | ✅ Rated |
| API 670 Compliance | Required | ✅ Compliant |
| Hazardous Area (ATEX/IECEx) | If required | ⚠ Verify with BN datasheet |
If your installation requires a different cable length, refer to the 330190 series part number matrix: the middle segment (e.g., -130-) denotes length in inches. Select accordingly and recalibrate the Proximitor sensor.

Replacement & Compatibility FAQ
Q: Can I use a 330190-080-00-05 cable instead of the 330190-130-00-05?
A: Only if the physical installation allows the shorter 80-inch length. You must recalibrate the Proximitor sensor for the new cable length, as gap voltage changes with cable capacitance.
Q: Is the 330190-130-00-05 compatible with the 3300 XL Proximitor?
A: Standard 3300 and 3300 XL series use different calibration curves. Cross-series use is not recommended without consulting Bently Nevada’s compatibility matrix.
Q: Can third-party extension cables replace this part?
A: Third-party cables may be used in non-API 670 applications if impedance, connector type, and temperature ratings match. For machinery protection systems, OEM parts are strongly recommended to maintain certification compliance.
Q: How do I verify the cable is functioning correctly after installation?
A: Measure the gap voltage at the Proximitor output with the probe at the correct gap distance. It should fall within the specified linear range (typically –10 VDC ± 0.5 V at nominal gap). Refer to the Bently Nevada calibration procedure for your specific probe/Proximitor combination.
Q: What is the lead time for this part?
A: In-stock units ship within 1–3 business days. Contact us for current inventory status.
