The Bently Nevada 330130-080-00-00, also cataloged as the 330130 Extension Cable, operates as a dedicated hardware component for RF signal transmission within 3300 XL Proximitor Sensor networks. It establishes the low-attenuation electrical path linking an eddy-current proximity probe to a remote processing transducer, enabling high-frequency displacement measurement execution without altering loop capacitance parameters.

The internal geometry of the 330130-080-00-00 cable maintains the precise physical parameters required to stabilize eddy-current probe scaling across its 8.0 m extension path. The continuous double-shielded design ensures proper cross-talk suppression when routed alongside adjacent instrumentation channels near high-speed machinery. This impedance control allows accurate gap voltage validation targeting standard -10 VDC operational baselines for structural rotor dynamics monitoring.
Q: Can an 8.0 m extension cable be combined with any standard probe length to form a functional transducer loop?
A: No. The total electrical length of the proximity probe and extension cable must match the specific configuration of the Proximitor sensor (typically tuned for 5.0 m or 9.0 m systems). Deviating from these engineered matched parameters introduces non-linear errors in the scale factor.
Q: What mitigation is required for the standard non-armored (-00) option when traversing open structural spans?
A: The non-armored option lacks native physical resistance to mechanical impacts or crushing forces. When deployed across open areas, it must be installed inside grounded steel conduits or liquid-tight metal raceways to protect the coaxial core from deformation.
