Bently Nevada 330130-080-12-05 3300 XL Standard Extension Cable

The Bently Nevada 330130-080-12-05, also cataloged as the 330130 Extension Cable, serves as the primary 3300 XL Standard Extension Cable utilized to execute non-contact displacement signal routing across 3300 XL 8 mm Proximity Transducer System platforms. The hardware functions as a calibrated electrical bridge, passing raw high-frequency signals between the 8 mm proximity probe and the corresponding Proximitor Sensor to capture dynamic vibration, static position, and shaft speed metrics.

Hardware Specifications

Coaxial Line Impedance and Cross-Talk Suppression

The 330130-080-12-05 cable incorporates the specialized FluidLoc matrix block to prevent fluid migration along the internal voids of the coaxial shielding. The transmission line is precision-tuned to maintain linear calibration profiles across API 670 standard parameters without requiring matching component bench setups. Strict coaxial concentricity delivers integrated cross-talk suppression when bundled into instrumentation trays, ensuring that gap voltage validation remains stable across the complete linear scale factor of the paired sensor network during complex rotor dynamics evaluation.

Frequently Asked Questions

Q: Does the interchangeability feature allow mixing this 8-meter cable with arbitrary 5-meter probes?

A: No. While components are physically interchangeable across the series, the total electrical length of the probe plus the extension cable must match the specific tuning configuration (typically 5.0 meters or 9.0 meters total) required by the Proximitor Sensor model in use.

Q: How does the FluidLoc construction alter the mechanical resilience of the cable?

A: The FluidLoc option seals the internal core structure, preventing oil or moisture from wicking through the cable into the junction box if the outer protective jacket suffers physical damage or abrasion within the machine casing.

Field Installation Guidelines

• Connector Protector Deployment: Ensure the integrated connector protector is correctly seated over the mated miniature coaxial connection. This mechanical barrier isolates the connection point from structural grounding and fluid exposure.

• Bend Geometry Enforcement: Observe standard minimum bend constraints during routing layout. Avoid crimping or crushing the cable sheath, as physical deformities modify the internal impedance profile and lead to signal reflection errors.

• Conduit Pulling Protocol: When pulling the 8.0-meter length through rigid conduits, pull via the cable body using proper mesh grips rather than pulling directly on the pre-terminated coaxial connectors to prevent stress failure of the internal contacts.
