Configured for high-frequency signal transmission in 3300 XL monitoring systems, the Bently Nevada 330130-085-00-05 (330130-085-00-05 Extension Cable) provides direct physical electrical continuity between the proximity probe and the Proximitor sensor.

Model Suffix Decomposition

The 330130-085-00-05 part number indicates the following hardware configuration:

• 330130: 3300 XL Extension Cable assembly.

• 085: 8.5 meters total system length requirement.

• 00: Standard connector type without protective housing options.

• 05: Agency approval configuration for hazardous locations.

Technical Hardware Specifications

Signal Integrity and Cross-Talk Suppression

The 3300 XL system relies on impedance-matched components to maintain measurement accuracy. The 330130-085-00-05 cable is constructed with internal shielding designed to minimize signal attenuation and mitigate electromagnetic cross-talk in multi-channel installations. To ensure signal integrity, the cable must not be spliced or shortened, as changes in length alter the electrical characteristics of the loop and invalidate the factory-set system scaling. Shield grounding should be verified at the monitor end to prevent potential ground loop currents that interfere with low-level displacement signals.

Field Installation Protocols

• Cable Routing: Route coaxial cables through dedicated metallic conduits to protect against mechanical impact and EMI.

• Bend Radius: Maintain a minimum static bend radius of 25 mm. Exceeding this limit will cause dielectric compression and impedance shifts.

• Connector Mating: Ensure the ClickLoc connectors are hand-tightened until fully seated. Use of tools is strictly prohibited to avoid structural damage to the interface.

• Support: Secure the cable at intervals not exceeding 500 mm to prevent vibration-induced movement at the connector junctions.

Frequently Asked Questions

• Q: Is this cable field-repairable if damaged?

  A: No. Any repair or modification to the coaxial cable changes its characteristic impedance, which renders the Bently Nevada system calibration inaccurate.

• Q: Does this cable work with 5-meter system configurations?

  A: No. The system must be calibrated for the specific total length (8.5 meters). Using this cable in a 5-meter system will cause gain and phase errors.

• Q: How does the agency approval suffix (05) affect usage?

  A: The 05 suffix indicates certification for hazardous area operations. Ensure local site safety regulations match this hardware certification.

• Q: What is the benefit of the ClickLoc connector design?

  A: It ensures a constant 75 Ohm impedance path and provides a vibration-resistant mechanical lock for consistent signal transmission.

• Q: Can I use this with non-Bently Nevada Proximitor sensors?

  A: No. The 3300 XL system is impedance-matched as a complete loop; third-party components will result in signal errors and loss of data.

• Q: How should I clean the connector contacts?

  A: Use only approved electronic contact cleaner. Do not use abrasive materials, as they will damage the gold plating and degrade electrical contact.

• Q: Does temperature affect the cable length?

  A: While physical length changes are negligible, cable impedance characteristics are thermally stable up to 177 deg C, ensuring reliable operation.

• Q: Why is the shield grounding important?

  A: It prevents external electromagnetic fields from inducing noise on the inner conductor, which is critical for measuring micron-level displacement.
