The Bently Nevada 330930-065-01-CN, also cataloged as the 330930 Extension Cable, operates as a dedicated hardware component for high-frequency electrical signal transmission within 3300 NSv proximity transducer platforms. The coaxial cable segment bridges the physical link between a 3300 NSv proximity probe and a 3300 NSv Proximitor sensor, sustaining the tight impedance metrics required to transmit non-contacting shaft displacement and vibration signals without phase distortion.

• -CN: Agency approval option specifying standard hazardous area certifications for China markets (Ex nA/Ex ia).

Cable Assembly Specifications

Eddy-Current Probe Scaling and Signal Transmission

The specific physical and capacitive layout of the 330930 coaxial line directly determines total loop impedance, dictating the accuracy of the system eddy-current probe scaling. When combined with a 3300 NSv 1.0 m probe, this 6.5 m line builds a calibrated 7.5 m system configuration necessary for proper gap voltage validation (-10 VDC targets). Maintaining fixed loop capacitance avoids signal attenuation at high carrier frequencies, verifying that small-target rotor dynamics tracking is unimpeded and satisfying cross-talk suppression criteria under parallel sensor routing constraints.

Procurement Package Inventory

• One (1) Bently Nevada 330930-065-01-CN 3300 NSv extension cable assembly

• Two (2) Removable silicone connector protection sleeves

• Factory verification certificate confirming baseline capacitance and dielectric isolation parameters

Mechanical Installation and Cabling Guidelines

• Route the braided stainless steel armored jacket along structural machine frames using insulated cable clamps to avoid sharp bends that distort internal coaxial spacing.

• Limit cable path bends to a minimum physical bend radius threshold of 25 mm to prevent structural cracking of the internal fluoropolymer dielectric layer.

• Push and twist the miniature ClickLoc coaxial connections firmly into their matching probe and sensor ports until a positive mechanical engagement occurs.

• Slide the provided silicone protection sleeves over the exposed coaxial connection interfaces to seal out water, oil, and airborne contaminants.

• Keep the extension cable shield completely isolated from local machine frames, running the structural loop shield to ground solely at the main instrumentation rack bulkhead terminal.

Logistics Framework & Cargo Handling

Delivery time: 2-7 days when payment finish, sent via premium international cargo channels handled by DHL, FEDEX, or UPS. The passive assemblies are packaged within sealed vapor-barrier anti-static industrial packaging sheets to protect the connector contacts from corrosion. Outer shipping containers use heavy-walled industrial cartons packed with shock-absorbing foam inserts to maintain factory electrical calibration parameters during transport loops.

Technical Engineering FAQ

Q: Can this 6.5 m 3300 NSv extension cable be spliced or cut in the field to adapt to short conduit layouts?

A: No. Splicing or changing the physical length of the coaxial cable alerts total loop capacitance and impedance. Doing so invalidates the factory eddy-current probe scaling matrix, making accurate calibration impossible and causing massive errors during gap voltage validation.

Q: Is this 3300 NSv extension cable compatible with a standard 3300 XL 8 mm proximity sensor?

A: No. The 3300 NSv series operates on distinct electrical tuning parameters compared to the 3300 XL series. Mixing components across series compromises the sensor loop calibration and causes the driver module to signal a constant "Not OK" system fault.

Q: Can this armored cable withstand continuous immersion in pressurized lubrication oil environments?

A: The fluoropolymer jacket provides chemical resistance to industrial lubricants. However, for continuous submersion under high static pressures, the connectors must be located outside the fluid boundary, or enclosed within oil-tight terminal junctions to prevent long-term fluid migration into the coaxial core.
