The Bently Nevada 330130-085-00-05, also cataloged as the 330130 Extension Cable, operates as a dedicated hardware component for RF signal transmission within 3300 XL Transducer System networks. The passive coaxial link maintains calibrated impedance matching parameters between the proximity probe and the Proximitor sensor, facilitating the propagation of high-frequency displacement signals without phase or amplitude distortion.

The internal 75 ohm coaxial design of the 330130-085-00-05 extension cable provides the precise electrical matching necessary for stable eddy-current probe scaling. By maintaining uniform capacitance and resistance profiles along the 8.5 metres run, the cable achieves high cross-talk suppression against adjacent machinery interference. This transmission accuracy enables precise gap voltage validation targeting standard -10 VDC baselines, preserving signal integrity for multi-channel rotor dynamics analysis.
Q: Can this 8.5 metres extension cable be altered or cut to fit specific enclosure layouts?
A: No. Shortening or changing the cable length alters the calibrated loop capacitance and electrical length. This directly shifts the linear scale factor of the paired Proximitor sensor, causing inaccurate displacement metrics.
Q: What structural limits apply to the standard cable design specified by the -00 suffix?
A: The -00 suffix indicates a standard coaxial jacket without an external stainless steel armor wrap or specialized FluidLoc barriers. It is designed for standard dry conduit runs where mechanical abrasion or direct liquid submersion is not present.
