Bently Nevada 330930-045-01-05 – Standard Extension Cable | 3300 XL Proximity Transducer System
Engineering Background
The Bently Nevada 3300 XL Series is the industry benchmark for continuous machinery protection and condition monitoring in rotating equipment applications. Deployed across power generation, oil & gas, petrochemical, and heavy industrial facilities worldwide, the 3300 XL system delivers the signal integrity and reliability demanded by API 670-compliant machinery protection systems.
Product Positioning
The 330930-045-01-05 is a factory-specified Standard Extension Cable engineered to bridge the 3300 XL proximity transducer and its paired proximitor/driver module. With a precisely controlled 4.5-meter (15-foot) cable length and matched system impedance, this cable is a critical passive component that directly affects gap voltage accuracy, sensitivity calibration, and overall system measurement integrity. It is not interchangeable with generic coaxial cable.

Engineering Advantages
- Factory-calibrated system matching: Ensures gap voltage linearity and sensitivity (200 mV/mil) are maintained without field recalibration
- Precision impedance control: Eliminates signal reflection errors that degrade measurement accuracy in long cable runs
- Robust mechanical construction: Armored jacket withstands vibration, chemical exposure, and high-temperature environments typical of turbomachinery installations
- Drop-in OEM replacement: Direct substitution for existing 330930-045-01-05 installations with zero system retuning required
- API 670 compliance: Supports machinery protection system certification and insurance requirements
System Architecture & Signal Flow
In a complete 3300 XL proximity measurement chain, the signal path is:
Proximity Transducer (probe tip) → Extension Cable 330930-045-01-05 → Proximitor Module → Monitor/System Rack
The extension cable carries the RF oscillator signal from the proximitor to the probe, and returns the modulated DC gap voltage back to the proximitor for demodulation. Cable length and impedance are fixed system parameters — substituting non-OEM cables will shift the system operating point and invalidate calibration, potentially causing false trips or missed alarms in machinery protection applications.

Technical FAQ
Q: Can I use a different length extension cable with my 3300 XL system?
A: No. The 3300 XL system is calibrated as a matched set (transducer + extension cable + proximitor). Changing cable length alters system impedance and invalidates factory calibration. Always replace with the identical part number.
Q: Is the 330930-045-01-05 compatible with both 8mm and 11mm 3300 XL probes?
A: Yes, provided the complete system (probe + cable + proximitor) is a matched 3300 XL assembly. Verify your proximitor model accepts this cable length.
Q: What is the difference between a Standard Extension Cable and an Armored Extension Cable in the 3300 XL series?
A: Standard cables use a flexible outer jacket suitable for most indoor and protected installations. Armored cables add a stainless steel braid for applications with severe mechanical abuse, chemical splash, or rodent exposure risk.
Q: Do you provide certificates of conformance or material traceability?
A: Yes. Certificates of conformance and available traceability documentation can be provided upon request. Contact support@konmask.com with your order number.
Q: What is the lead time for the 330930-045-01-05?
A: In-stock units typically ship within 1–3 business days. Contact us for urgent requirements or volume orders.
