The Bently Nevada 330130-075-00-05, also cataloged as the 330130 Extension Cable, operates as a dedicated hardware component for signal transmission between proximity probes and Proximitor sensors within 3300 XL transducer systems.

Model Configuration Matrix

• Model: 330130 (3300 XL Standard Extension Cable)

• Cable Length: 7.5 meters (24.6 feet)

• Cable Type: Standard

• Agency Approval: 05 (CSA, ATEX, IECEx)

Hardware Specifications

Rotor Dynamics and Signal Integrity

The 3300 XL system relies on precise impedance matching to maintain eddy-current probe scaling. This extension cable is engineered to ensure signal attenuation remains within defined thresholds, supporting accurate gap voltage validation at the -10 VDC target. Proper installation requires adherence to the minimum bend radius of 25.4 mm (1.0 in) to prevent changes in dielectric characteristics. Cross-talk suppression is maintained by proper shielding practices; ensure the cable shield is continuous and correctly grounded at the Proximitor sensor location to prevent ground loops that interfere with rotor dynamics monitoring.

Ordering Information

• 330130-075-00-05 Extension Cable unit

• Integrated Miniature ClickLoc connectors (factory installed)

• Protective cable jacket material: FEP insulation

• Note: Calibration documentation and mounting clips are not included unless specified separately

Field Installation Guidelines

• Routing: Avoid proximity to high-voltage conduits to prevent electromagnetic interference (EMI) coupling into the 75 Ohm signal path.

• Bend Radius: Adhere strictly to the 25.4 mm (1.0 in) minimum bend radius limit to avoid mechanical stress on the coaxial dielectric.

• Connector Handling: Use an appropriate torque tool (0.565 N m) for tightening connectors to prevent thread deformation or insufficient contact pressure.

• Shielding: Ensure the cable shield is properly terminated at the monitoring system interface to preserve signal integrity.

• Securement: Use industrial-grade cable ties at consistent intervals to prevent cable whipping or mechanical fatigue in high-vibration areas.

Logistics and Handling

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

• Shipping: Via DHL, FEDEX, or UPS.

• Packaging: All items are shipped using anti-static industrial packaging to maintain product integrity and prevent electrostatic discharge.

Frequently Asked Questions

• Q: Can I modify the cable length?

  A: No, the system is impedance-matched for the specific length. Altering the cable length will invalidate the system calibration.

• Q: Is this cable compatible with non-XL Proximitor sensors?

  A: Yes, the 3300 XL extension cables are backward compatible with standard 3300 series transducer systems.

• Q: What is the maximum torque for connectors?

  A: The maximum torque is 0.565 N m (5 in lbf); exceeding this can damage the gold-plated contact surfaces.

• Q: What is the insulation material?

  A: The standard cable is insulated with fluoroethylenepropylene (FEP).

• Q: How should the cable be cleaned?

  A: Use only non-residue electronic cleaners. Avoid solvents that may degrade the FEP jacket.

• Q: Does the cable require specific grounding?

  A: The cable shield should be grounded only at the Proximitor sensor end to avoid creating ground loops.

• Q: Can this cable be used in hazardous areas?

  A: Yes, this model includes CSA, ATEX, and IECEx approvals.

• Q: What is the purpose of the 75 Ohm impedance?

  A: It is required to match the impedance of the probe and the Proximitor sensor to prevent signal reflections.
