The Bently Nevada 330130-030-00-05, also cataloged as the 330130 Extension Cable, operates as a dedicated hardware component for high-frequency signal transmission within 3300 XL Proximity Transducer System networks. It matches the electrical capacitance and impedance of 3300 XL proximity probes to convey dynamic shaft position and vibration signals directly to downstream Proximitor signal processing hardware.

The 330130-030-00-05 extension cable maintains tight physical and electrical tolerances to preserve eddy-current probe scaling accuracy across severe machinery monitoring loops. During commissioning, gap voltage validation (-10 VDC targets) measured at the Proximitor test points verifies static mechanical alignment relative to the target shaft. The continuous 75 ohm triaxial shielding enforces cross-talk suppression and isolates microvolt-level high-frequency signals from severe electromagnetic noise generated under dynamic rotor dynamics conditions.
Q: How does combining a 3.0 metre extension cable integrate into standard 3300 XL transducer configurations?
A: Combining this 3.0 metre extension cable with a 2.0 metre proximity probe head creates a total electrical system length of 5.0 metres, perfectly matching the input calibration tuning of 5.0 metre Proximitor units.
Q: What precautions should be taken with ClickLoc miniature coaxial connectors during field assembly?
A: Ensure connector mating faces are completely free of oil, water, or particulate contamination before engagement. Tighten by hand until a positive mechanical lock is felt; do not use wrenches or mechanical tools.
