The Bently Nevada 330130-040-12-CN, 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 physical shaft position and vibration signals directly to downstream Proximitor signal processing hardware.

The 330130-040-12-CN extension cable maintains tight electrical parameters to ensure accurate eddy-current probe scaling across dynamic machinery monitoring loops. Field commissioning requires gap voltage validation (-10 VDC targets) measured at the Proximitor output terminals to verify the mechanical center point of the target shaft relative to the probe face. The 75 ohm triaxial construction provides cross-talk suppression and isolates high-frequency signal paths from surrounding electromagnetic noise generated during severe rotor dynamics.
Q: What is the primary functional advantage of the FluidLoc cable configuration (Option 12)?
A: The FluidLoc cable construction prevents oil and liquid hydrocarbon ingress from wicking through the internal coaxial wire strands and migrating outside the machine housing.
Q: How does combining a 4.0 metre extension cable affect overall transducer system calibration?
A: Combining this 4.0 metre extension cable with a 1.0 metre probe head creates a 5.0 metre total electrical system length, matching the required calibration parameters of standard 5.0 metre Proximitor modules.
