Bently Nevada 330854-040-24-05 Extension Cable

Bently Nevada 330854-040-24-05 Extension Cable

The Bently Nevada 330854-040-24-05, also cataloged as the 3300 XL Extension Cable, operates as a dedicated hardware component for signal transmission between the proximity probe and the Proximitor sensor within TSI (Turbomachinery Supervisory Instrumentation) systems.

Suffix Breakdown & Model Matrix

Hardware Specifications

Mechanical Monitoring & TSI Integration

The 3300 XL extension cable is engineered for optimal eddy-current probe scaling by maintaining precise impedance characteristics essential for signal fidelity. When integrated into rotor dynamics monitoring chains, the cable ensures consistent electrical performance, supporting the gap voltage validation required to maintain a nominal -10 VDC center-point. The cable’s design provides robust cross-talk suppression through high-quality shielding, which prevents electromagnetic interference from corrupting the dynamic vibration and static position signals processed by the Proximitor sensor.

Frequently Asked Questions

Q: Is this extension cable compatible with standard 3300 series Proximitor sensors?

A: Yes. The 3300 XL extension cable is designed for full backward compatibility and interchangeability with other non-XL 3300 series 5 mm and 8 mm transducer system components.

Q: Can the cable be shortened if the required length is less than 4.0 meters?

A: No. Field modification of the cable length is strictly prohibited, as it alters the system impedance and capacitive loading, which will invalidate the calibrated output and measurement accuracy of the transducer system.

Field Installation Guidelines

• Connector Engagement: Use the ClickLoc connector system to ensure a secure, vibration-resistant connection. Verify that the connector is fully locked to prevent signal intermittency.
• Cable Protection: Route the cable through protective conduit where exposed to mechanical hazards or harsh chemical environments. Do not exceed the minimum bend radius of the coaxial cable.
• EMI Mitigation: Maintain physical separation between the extension cable and high-power AC motor leads or VFD cabling to prevent induced signal noise.
• Grounding: Ensure that all cable connections are kept clean and dry. The shield continuity is maintained through the connector housing; ensure no conductive debris compromises the connection.
