Bently Nevada 330130-045-02-00 3300 XL Extension Cable

Configured for signal transmission between eddy-current transducers and monitoring instrumentation in machinery protection systems, the Bently Nevada 330130-045-02-00 (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 maintains the characteristic impedance required for the 3300 XL proximity transducer system. Proper system operation relies on gap voltage validation, with target values typically centered at -10 VDC within the linear operating range. Deviations in cable length or impedance mismatch directly affect the accuracy of rotor dynamics measurements. The design utilizes high-frequency shielding to provide cross-talk suppression in industrial environments, preventing external electromagnetic interference from introducing noise into the transducer signal path.

Frequently Asked Questions

Q: Can this cable be trimmed to accommodate specific installation distances?

A: No. The system is impedance-matched as a complete chain consisting of a probe, extension cable, and Proximitor. Modifying the cable length alters the electrical path and requires factory-level reconfiguration.

Q: What is the recommended method for securing the connector interfaces?

A: Connectors must be finger-tightened only. Use of pliers or other mechanical tools may damage the coaxial structure and result in signal drift or increased noise floor.

Field Installation Guidelines

1. Verify that all system power is isolated before disconnecting or connecting transducer components.
2. Ensure the minimum bend radius of the cable is strictly maintained to prevent damage to the internal dielectric and shielding.
3. Utilize the included connector protectors to prevent the ingress of conductive dust or moisture at the junction points.
4. Route the cable within dedicated conduit, maintaining a minimum separation of 300 mm from high-voltage AC cabling to prevent induced noise.
5. Confirm the total system length matches the configuration parameters set in the monitoring hardware to ensure correct mV/mm scale factors.
