Configured for Specific Technical Task in System/Network Name, the Bently Nevada 330930-040-00-05 (330930 Extension Cable) provides direct physical/electrical execution. It serves as a calibrated transmission bridge between a 3300 NSv proximity probe and a Proximitor sensor, routing high-frequency radio frequency (RF) signals without altering loop impedance boundaries.

Configuration Options Matrix

• 330930: Base model identification for the 3300 NSv system-compatible extension cable.
• -040: Cable Length Option designating a 4.0 meters (13.1 feet) operational span.
• -00: Connector Protector and Cable Option specifying a standard coaxial build without stainless steel armor.
• -05: Agency Approval Option acquiring multiple hazardous location certifications.

Hardware Specifications

Eddy-Current Probe Scaling and Signal Stabilization

The 330930-040-00-05 balances specific electrical values to ensure consistent eddy-current probe scaling metrics across the entire transducer loop. The 69.9 pF/m electrical capacitance acts directly on the target driver circuit, facilitating accurate gap voltage validation against the standard -10 VDC targets. This structural matching provides high-frequency cross-talk suppression between close-proximity channels while preserving phase accuracy for advanced rotor dynamics evaluation.

Packaged Materials List

• 1 x Bently Nevada 330930-040-00-05 Coaxial Extension Cable (4.0 meters)
• 2 x Silicon Connector Protection End Caps

Physical Routing Instructions

• Minimum Bend Diameter Limits

  Route the unarmored coaxial line ensuring the path does not drop below a 25.4 mm (1.0 inch) bend radius to prevent internal dielectric deformation.

• Isolation Barrier Placement

  Run the cable through dedicated, grounded metal conduits separate from high-power AC lines to suppress external electromagnetic fields.

• ClickLoc Connection Torque

  Join the coaxial fittings by hand until the ClickLoc detent engages fully; never apply mechanical pliers or wrenches to these miniature pins.

• Terminal Casing Drainage

  Arrange the low points of the conduit layout with liquid drains to prevent moisture pooling around the unarmored outer jacket.

Frequently Asked Questions

• Can this extension cable be cut down or spliced in the field if the physical pathway is shorter than 4.0 meters?

  No. Altering the physical length changes the loop capacitance, which completely shifts the eddy-current probe scaling and ruins calibration.

• Is it safe to disconnect this extension cable from the Proximitor while the monitoring rack is powered?

  Yes. The line carries low-voltage RF signal current, but disconnecting it will instantly trigger a loop fault log and open-circuit alarm.

• What happens if an unarmored cable version comes into direct contact with pooling industrial synthetic oil?

  The outer fluoropolymer jacket resists common machine lubricants, but lack of armor means it must be run in conduit to avoid physical cuts.

• Does this cable structure support cross-talk suppression if run alongside identical 3300 NSv extension links?

  Yes, the coaxial shielding controls internal fields, but maintaining physical separation inside the tray prevents parasitic signal capacitive coupling.

• How can a technician verify that the cable assembly has maintained its nominal 50 ohm output resistance?

  Disconnect both ends of the loop and measure continuity across the center pin and outer shield using a calibrated digital ohm meter.

• Will a mismatch in overall system length impact the target gap voltage validation window?

  Yes. The driver relies on a total calibrated system length; an incorrect cable length prevents the loop from settling at the -10 VDC target.

• What is the primary indicator that the internal dielectric core has suffered a compression crush injury?

  The monitor displays a significant shift in gap voltage readings or shows intermittent noise spikes during normal machine rotor dynamics operation.

• Are specialized tools required to lock the miniature coaxial ClickLoc interfaces together?

  No. The ClickLoc mechanism joins with a simple push-and-turn action, and using hand tools on the assembly risks striping the thin outer ring.
