Bently Nevada 330130-040-00-00 – Proximity Transducer Extension Cable | 3300 Series Platform
Engineering Background
The Bently Nevada 3300 Series Proximity Transducer System is the global standard for non-contact vibration and position measurement in rotating machinery. Deployed across gas turbines, steam turbines, compressors, and pumps in power generation, oil & gas, and petrochemical facilities, the system’s three-component architecture—probe, extension cable, and proximitor—demands precision-matched interconnects to preserve signal integrity across the full measurement chain.
Product Positioning
The 330130-040-00-00 is a factory-specified extension cable engineered to bridge the 3300 Series eddy-current probe to its companion proximitor/driver module. At 40-inch (approximately 1.0 m) nominal length, it occupies the mid-range of the 3300 cable family, making it the preferred choice for installations where the probe-to-junction-box run falls within standard panel-mount configurations. Every electrical parameter—impedance, capacitance, and shielding—is matched to the 3300 system calibration to ensure the proximitor’s output voltage accurately represents shaft displacement without field recalibration.

Proven Application Environments
- Gas & Steam Turbines – Shaft radial vibration and axial position monitoring per API 670 requirements
- Centrifugal & Axial Compressors – Continuous rotor dynamic surveillance in upstream and midstream compression trains

Engineering Advantages
- System-Matched Calibration – Electrical characteristics (impedance, capacitance per unit length) are factory-matched to the 3300 proximitor, preserving the ±1% full-scale accuracy of the measurement chain without site adjustment.
- Double-Shield EMI Rejection – Braided outer shield plus foil inner shield attenuates electromagnetic interference from VFDs, switchgear, and high-current bus runs common in industrial plants.
- OEM Connector Terminations – Factory-crimped, gold-plated coaxial connectors eliminate field-soldered joints—the leading cause of intermittent signal faults in proximity systems.
- Wide Thermal Range – Rated to –40 °C / +85 °C, suitable for arctic outdoor installations and hot-section junction boxes near turbine casings.
- Drop-In Replacement – Identical form, fit, and function to OEM-installed cables; no wiring diagram changes or system re-commissioning required.
- API 670 Compliant – Meets the cable specification requirements of the industry’s primary machinery protection standard.
System Architecture & Signal Flow
The 3300 Series operates as a three-component eddy-current measurement chain:
- Probe (Sensor) – Generates a high-frequency electromagnetic field; target displacement modulates the field impedance.
- Extension Cable (330130-040-00-00) – Transmits the modulated RF signal from the probe tip to the proximitor with minimal attenuation and zero impedance mismatch.
- Proximitor / Driver Module – Demodulates the RF signal and outputs a DC voltage proportional to gap distance (typically –200 mV/mil or –7.87 V/mm).
Substituting a non-matched cable alters the system’s total cable capacitance, shifting the proximitor’s linear range and introducing a static measurement offset that cannot be corrected by zero adjustment alone. The 330130-040-00-00 eliminates this risk by maintaining the exact electrical length specified in the 3300 system calibration.
Sourcing & Quality Verification
- All units sourced from authorized distributors or verified surplus channels with full traceability documentation.
- Each cable undergoes incoming inspection: connector continuity, shield integrity, and visual inspection for jacket damage or connector corrosion.
- Original manufacturer labeling and part number markings preserved and verified against Bently Nevada part number structure.
- Certificates of conformance (CoC) and test reports available upon request for critical-service applications.
- Packaging: anti-static bag, coiled with minimum bend radius maintained, boxed with foam protection.
Procurement Process
- Confirm Compatibility – Verify your probe model (8 mm or 11 mm) and proximitor series against the 330130-040-00-00 compatibility matrix above.
- Check Cable Length – The total probe + extension cable length must equal the system-calibrated length (typically 5 m, 9 m, or custom). Confirm your installation geometry before ordering.
- Place Order – Add to cart and complete checkout. Volume pricing available for MRO stocking orders ≥ 5 units—contact us for a quote.
- Receive & Inspect – Inspect upon receipt. Report any discrepancies within 48 hours of delivery.
- Install & Commission – Follow Bently Nevada Installation Manual for 3300 Series. No recalibration required when replacing a like-for-like cable.
Lead time: In-stock units ship within 1–3 business days. For urgent plant shutdowns or turnaround requirements, contact support@konmask.com or call +0086 19859288691 for expedited handling.
Technical FAQ
Q: Can I use a standard coaxial cable as a substitute?
A: No. Standard RG-type coaxial cables have different capacitance-per-unit-length values that will shift the proximitor’s linear range and introduce a measurement offset. Only Bently Nevada-specified extension cables should be used.
Q: What is the total system cable length when using this extension?
A: The 330130-040-00-00 is 40 inches (≈ 1.016 m). It must be combined with a probe integral cable to reach the system-calibrated total length. Consult your proximitor’s calibration certificate for the required total length.
Q: Is this cable compatible with the 3500 Series?
A: No. The 3500 Series uses a different connector and cable specification. The 330130-040-00-00 is designed exclusively for the 3300 Series platform.
Q: Do you provide a warranty?
A: Yes. We offer a 90-day warranty against defects in materials and workmanship. Units confirmed defective will be replaced or refunded at our discretion.
Q: Can I order a custom cable length?
A: Custom lengths are available for project-specific requirements. Contact us with your total system cable length requirement and probe model for a custom quotation.
