Bently Nevada 330130-040-01-00 3300 XL Extension Cable

Configured for signal transmission between eddy-current transducers and monitoring instrumentation in machinery protection systems, the Bently Nevada 330130-040-01-00 (330130 Extension Cable) provides direct physical signal path continuity for proximity measurement chains.

Hardware Specifications

Eddy-Current Probe Scaling and Signal Integrity

The 330130 extension cable is a calibrated component of the 3300 XL proximity transducer system. It is constructed to maintain a specific characteristic impedance to ensure proper system-level scaling. Any change in the total length of the transducer-extension cable-proximitor configuration alters the output sensitivity. The system requires a nominal -10 VDC gap voltage validation at the midpoint of the linear range to ensure accurate rotor dynamic monitoring. Users must ensure that cable connections are protected from moisture and contaminants to prevent signal attenuation or drift in gap voltage measurements. Cross-talk suppression is maintained through integrated shielding throughout the cable assembly.

Frequently Asked Questions

Q: Can this extension cable be used with non-3300 XL series probes?

A: No. The 3300 XL components are impedance-matched as a complete system. Using this cable with legacy 3300 or 7200 series components will result in incorrect scale factors and loss of calibration accuracy.

Q: Are there specific torque requirements for the connector interfaces?

A: Yes. Connectors must be finger-tightened only. Use of tools to overtighten may damage the connector threads or internal pin alignment, resulting in intermittent signals or high-frequency noise.

Field Installation Guidelines

1. Ensure all system power is isolated before disconnecting or connecting transducer components to prevent electrical transients.
2. Route the extension cable through conduit or dedicated cable trays to prevent mechanical damage. Ensure the minimum bend radius is not exceeded to avoid stressing the internal conductor.
3. For armored cable variants, ensure the armor is properly grounded at the junction box or entry point if specified by local electrical codes to maintain shielding effectiveness.
4. Clean all connector pins with an appropriate contact cleaner if exposure to oils or moisture occurred during installation.
5. Verify the total system length (Probe + Extension Cable) matches the configuration programmed in the monitor or proximitor module.
