The Bently Nevada 330130-040-12-00 serves as the primary 330130 Standard Extension Cable utilized to execute non-contacting displacement and vibration measurements across 3500 Machinery Protection System platforms. It transmits radio frequency signals between a 3300 XL 8 mm proximity probe and a matching Proximitor sensor without altering critical loop impedance.

Hardware Model Composition

• 330130: 3300 XL Standard Extension Cable

• -040: Cable length option (4.0 m / 13.1 ft)

• -12: Connector and cable option (Standard coaxial cable with stainless steel armor sleeve and connector protectors)

• -00: Agency approval option (No hazardous area certifications required)

Technical Performance Matrix

Eddy-Current Probe Scaling and System Calibration

The coaxial hardware architecture directly affects the eddy-current probe scaling by maintaining a fixed electrical impedance loop. This balanced feedback loop allows precise field gap voltage validation (-10 VDC targets) within the center of the calibrated displacement profile. The outer stainless steel armored sleeve provides mechanical containment that isolates the inner signal core, ensuring absolute cross-talk suppression when routed alongside parallel sensor circuits on the machine casing.

Dispatched Kit Items

• 1 x Bently Nevada 330130-040-12-00 Armored Extension Cable

• 2 x Factory-terminated miniature coaxial clickloc connectors

• 1 x Integrated thick-walled silicone connector protector kit

• 1 x Technical documentation sheet with physical grounding schematic

Field Routing Regulations

• Armor Clearance Check: Route the flexible stainless steel armor body without contacting sharp chassis corners or vibrating casing edges to eliminate friction wear.

• Coaxial Connector Engagement: Join the miniature clickloc male and female interfaces by hand until a positive physical latch is fully achieved.

• Bend Boundary Constraints: Do not force the armored line into a bend radius tighter than 25.4 mm (1.0 in) during permanent physical mounting.

• Single-Point Ground Separation: Keep the extension cable outer armor electrically isolated from intermediate machine structures, grounding solely at the Proximitor side.

Engineering FAQ

• Does this specific extension cable modify the calibrated scale factor of the sensor loop?

  No. This component operates as a passive transmission path with tailored electrical parameters. When combined with an 8 mm probe, it preserves the factory 7.87 V/mm scale factor.

• Can this hardware module be hot-swapped while the primary machinery monitor is live?

  Yes, the cable can be uncoupled while the system loop is powered. However, the resulting open-circuit voltage parameter will trip monitoring alerts if bypass locks are not active.

• What physical protection is offered by the -12 option selection?

  The -12 option configures a flexible, continuous stainless steel armor wrap over the FEP cable core, combined with pre-installed fluid-resistant protectors for the coaxial junctions.

• What system error occurs if the 4.0 m cable length is arbitrarily shorted or modified?

  Splicing or modifying the length changes the total loop capacitance. This throws off the tuned operating frequency of the Proximitor, invalidating the calibration profile.

• Does this extension cable require a separate power supply connection from the rack backplane?

  No, this hardware is entirely passive. It handles radio frequency excitation current generated and interpreted exclusively by the connected external Proximitor module.

• How does the FEP jacket composition react to aggressive industrial fluids?

  The Fluorinated Ethylene Propylene outer jacket provides complete isolation against moisture ingress, synthetic turbine oils, chemical solvents, and petroleum byproducts.

• Is an independent ground strap required for the armored casing of this cable?

  No. The armored casing is design-isolated from structural machine grounds. It must ground cleanly through the terminal connection point at the Proximitor sensor chassis block.

• What are the absolute temperature limits for this cable during continuous operation?

  The internal dielectric layers, silver-plated core, and external armored assembly are rated to sustain continuous structural exposure from -51 deg C up to +177 deg C.
