Configured for high-frequency signal transmission in 3300 XL 8mm Proximity Transducer Systems, the Bently Nevada 330909-00-80-10-02-05 (330909-00-80-10-02-05 Proximity Probe Cable) provides direct electrical connectivity between the proximity probe and the Proximitor sensor. This component maintains the required characteristic impedance for signal propagation and mechanical gap measurement.

Model Configuration Reference

The 330909-00-80-10-02-05 identifies a specific cable assembly length and construction standard within the 3300 XL 8mm system. The part number denotes a fixed-length coaxial configuration calibrated for specified loop resistance. Modifications to the physical length or shielding configuration of this assembly are not permitted, as such changes affect the transducer system's calibrated output voltage per unit of displacement.

Hardware Specifications

Bently Nevada TSI Mechanical Monitoring Characteristics

The probe cable is a passive impedance-matching component integral to the eddy-current probe scaling process. It maintains the signal path integrity required for -10 VDC gap voltage validation at the Proximitor. The coaxial construction is optimized to minimize signal attenuation and cross-talk suppression in proximity-based shaft monitoring. When integrated into the 3300 XL architecture, the cable ensures the linearity of the transducer system across the full range of rotor dynamics, preventing phase shifts that could compromise vibration analysis.

Ordering Info

• Cable assembly includes the 330909-00-80-10-02-05 unit.

Field Installation Guidelines

• Maintain the manufacturer-specified minimum bend radius to prevent stress on the internal coaxial center conductor.

• Secure the cable using non-metallic clamps to prevent contact-induced signal interference or mechanical fatigue.

• Ensure connector mating surfaces are cleaned with an appropriate electronic contact cleaner prior to coupling.

• Torque the connection to the specified value; excessive force may damage the connector threads or the internal sealing O-ring.

• Utilize dedicated instrument cable trays to prevent electrical noise coupling from power conductors.

Technical FAQ

• What is the impact of cable length on system calibration?

  The cable length is part of the system impedance; changing the length without re-calibrating the Proximitor will result in significant measurement errors.

• Can this cable be spliced if damaged?

  Splicing is not recommended. Any physical alteration to the coaxial cable changes the impedance, rendering the transducer system invalid.

• How is the IP67 rating maintained?

  The rating is maintained by the integrated rubber seals and the secure engagement of the threaded coaxial connectors.

• What type of signal does this cable carry?

  The cable carries high-frequency radio signals generated by the Proximitor sensor to the probe tip.

• Are there specific grounding requirements?

  The cable shield should be grounded only at the specified system ground point to prevent ground loops.

• Does this cable require specific shielding?

  The cable is inherently shielded by its coaxial construction, which is required for operation in high-EMI environments.

• What should be done if the connector threads are worn?

  Worn connectors should be replaced immediately, as they cannot guarantee the physical contact required for low-impedance signal transmission.

• How do I identify if the cable is degraded?

  Degradation is typically identified by an unstable gap voltage or an intermittent "Transducer Fault" status in the monitoring rack.
