Configured for high-frequency signal transmission in 3300 XL 8 mm Proximity Transducer Systems, the Bently Nevada 330910-00-05-50-02-00 (330910-00-05-50-02-00 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 across rotating machinery interfaces.

Configuration Reference

The 330910-00-05-50-02-00 part number denotes a specific cable assembly length and construction standard within the 3300 XL 8 mm system. The string identifies the 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 Information

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 electronic contact cleaner prior to coupling.

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

• Utilize dedicated instrument cable trays to prevent electrical noise coupling from high-voltage 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 measurement errors.

• Can this cable be spliced if damaged?

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

• How is the environmental 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 must be replaced, as they cannot guarantee the physical contact required for low-impedance signal transmission.

• How is degradation identified?

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