The Bently Nevada 330730-080-12-00, also cataloged as the 330730 11mm Extension Cable, operates as a dedicated hardware component for transmitting high-frequency RF signals between an eddy-current proximity probe and a sensor housing within 3300XL Proximity Transducer System platforms.

Physical and Electrical Parameters

Eddy-Current Signal and Transducer Scaling

The 330730-080-12-00 cable maintains precise electrical impedance matching to stabilize eddy-current probe scaling over long distances. It ensures that the overall 3300XL 11mm transducer system outputs a linear scale factor of 3.94 V/mm (100 mV/mil) when targets are positioned within the designated linear range. The inclusion of the FluidLoc cable option prevents moisture and process fluids from wicking through the cable interior, eliminating signal attenuation and mitigating cross-talk suppression issues between adjacent machine monitoring channels. This structural integrity prevents drift in the baseline gap voltage validation targets during high-amplitude rotor dynamics events.

Technical Engineering FAQ

Q: What is the primary purpose of the FluidLoc cable option on this model?

A: The FluidLoc option features an internal sealing mechanism that blocks the migration of fluids, oils, and gases through the inside of the cable, ensuring signal integrity in harsh environments.

Q: How does this extension cable impact system calibration?

A: This cable is tuned specifically for the 3300XL 11mm proximity system. Altering the physical cable length or mixing it with 5mm/8mm system components will distort the impedance, causing false gap voltage readings and violating the 3.94 V/mm scale factor calibration.

Q: Does the integrated connector protector affect physical clearance during routing?

A: Yes, the integrated connector protector adds a ruggedized outer diameter to the connection point, which requires proper conduit sizing or clearance considerations during pull-through installation.

Field Installation Guidelines

• Minimum Bend Radius: Do not exceed the minimum allowable bend radius of 25.4 mm (1.0 inch) during routing to prevent internal coaxial dielectric deformation.
• Shield Grounding: Ensure the extension cable shield isolates cleanly from structural machine ground. The shield must connect to ground strictly at the Proximitor sensor housing terminal block.
• Connector Torque: Finger-tighten the coaxial connectors, then use specialized tools to apply the manufacturer-specified torque. Do not use standard pliers, which can deform the gold-plated pins.
• Conduit Isolation: Route the extension cable through dedicated, isolated conduit channels to prevent electromagnetic interference from high-voltage motor or generator power lines.
