Description

The Bently Nevada 330130-045-00-00, also cataloged as the 330130 3300 XL Extension Cable, operates as a dedicated hardware component for physical signal transmission within a Bently Nevada 3300 XL 8mm Proximitor Sensor loop. The cable links the proximity probe to the Proximitor sensor unit, completing the tuned radio-frequency circuit without altering system impedance.

Hardware Specifications

Machinery Monitoring and TSI Characteristics

The 330130-045-00-00 provides the precise capacitance and electrical length required to sustain accurate eddy-current probe scaling across the transducer assembly. When combined with a 0.5 meter probe, this 4.5 meter extension cable completes the standard 5.0 meter system length, matching the calibration matrix needed for gap voltage validation (-10 VDC targets). Maintaining exact physical cable lengths prevents impedance variations that would otherwise degrade the resolution of high-frequency rotor dynamics, ensuring clean vibration waveforms are routed back to the monitoring system.

Frequently Asked Questions

Q: What does the -045 designation represent in the complete part number?

A: The -045 option indicates a specific physical cable length of 4.5 meters, which completes the required 5.0 meter total system length when mated to a 0.5 meter proximity probe.

Q: Can the cable be trimmed or spliced in the field if it is too long?

A: No. Splicing or changing the physical length of the coaxial cable permanently alters the system capacitance, rendering the factory calibration invalid and introducing severe errors into the vibration readings.

Field Installation Guidelines

• Minimum Bend Radius: Do not exceed a minimum bend radius of 25.4 mm (1.0 inch) during routing to prevent internal dielectric damage or kinking of the coaxial shield.
• Connector Integrity: Ensure the gold-plated ClickLoc connectors are completely dry and free from contaminants before joining them. Push and twist until the tactile click is felt, indicating a locked interface.
• Conduit Protection: Route the extension cable inside dedicated metal conduit or cable trays to isolate the signal from physical impact and strong electro-magnetic fields generated by nearby power cables.
