Configured for high-frequency signal propagation within 3300 XL NSv Proximity Transducer Systems, the Bently Nevada 330930-065-00-05 (330930-065-00-05 Extension Cable) provides direct electrical connectivity between the proximity probe and the monitoring interface. This hardware component maintains specific loop impedance required for millivolt-per-unit gap measurement.

Suffix Breakdown & Model Matrix

The 330930-065-00-05 part number specifies a distinct cable length and shielding configuration optimized for NSv (Near-field) transducer applications. The "065" suffix indicates a fixed length of 6.5 meters, while the "00-05" suffix delineates specific connector and jacket standards. No variance in mechanical length or impedance tolerance is permitted for this part number, as system calibration is dependent on the original factory-defined loop resistance.

Hardware Specifications

Bently Nevada TSI Mechanical Monitoring Characteristics

This extension cable is a passive component of the eddy-current probe scaling circuitry. It is calibrated to ensure that gap voltage validation remains within the -10 VDC target range at the proximity sensor interface. The coaxial construction is engineered for effective cross-talk suppression in high-density rack configurations, ensuring that vibration signals from adjacent channels do not interfere with raw transducer inputs. Proper impedance matching is maintained throughout the signal path to support accurate rotor dynamics data acquisition without phase shift or signal attenuation.

Field Installation Guidelines

Connector Handling

• Use only approved tools to tighten threaded connectors to the specified torque.

• Ensure connector mating surfaces are free of contaminants or oils to prevent contact resistance.

Cable Routing

• Maintain a minimum bend radius of 2.5 cm to prevent damage to the internal coaxial core.

• Secure the cable using non-conductive, vibration-resistant cable ties.

• Route cables in isolated conduits to prevent electromagnetic interference from secondary power lines.

Logistics and Handling

• Delivery time: 3-5 days when payment finish.

• Shipping via DHL, FEDEX, or UPS.

• Every unit is shipped in high-grade anti-static industrial packaging to prevent electrostatic discharge and mechanical shock.

Frequently Asked Questions

Q: Can this cable be trimmed to fit a shorter installation distance?

A: No, trimming the cable will alter the loop impedance and capacitance, resulting in a loss of calibration accuracy for the transducer system.

Q: What is the significance of the 6.5 meter designation?

A: The total system length includes the probe, extension cable, and Proximitor; the 6.5 meter length is a fixed parameter for impedance-based signal scaling.

Q: How is the shield grounded in this configuration?

A: The cable shield should be tied to the instrument ground at the monitoring rack to prevent ground loops that introduce signal noise.

Q: Is this component field-repairable?

A: No, the cable assembly is a sealed unit; internal conductor damage or connector failure requires complete assembly replacement.
