Bently Nevada 330130-040-00-05 3300 XL 8 mm Extension Cable

Configured for signal transmission in 3500 Machinery Protection System platforms, the Bently Nevada 330130-040-00-05 (330130 Sensor Extension Cable) provides direct physical/electrical execution. This hardware component bridges the high-frequency radio frequency (RF) circuit between a 3300 XL 8 mm proximity probe and a matching Proximitor Sensor, preserving loop impedance for proximity transduction.

The complete model nomenclature breakdown for this technical configuration is defined below:

• 330130: Base model identifier for the 3300 XL 8 mm Extension Cable system.

• 040: Cable Length Option designating 4.0 meters (13.1 feet) of coaxial line.

• 00: Connector Protector and Cable Option specifying standard coaxial cable without terminal protectors.

• 05: Agency Approval Option designating multiple regional certifications including CSA, ATEX, and IECEx intrinsic safety mandates.

Hardware Specifications

Eddy-Current Probe Scaling and Cross-Talk Suppression

Mechanical deployment of this 4.0-meter extension cable configuration relies on precise impedance calibration to safeguard rotor dynamics tracking data. The 4.0-meter length is combined with a matching 1.0-meter probe length to establish a definitive 5.0-meter system length engineered to maintain the factory eddy-current probe scaling factor of 7.87 V/mm (200 mV/mil). The integrated coaxial braid provides active cross-talk suppression, preventing capacitive coupling or signal interference when routed adjacent to separate high-density instrument bundles inside the machinery conduit track.

Frequently Asked Questions

Q: How does the Option 05 agency approval modify the hardware field electrical configuration?

A: Option 05 indicates certified compliance for explosive atmospheres under ATEX, IECEx, and CSA frameworks. Field installation requires routing the extension line through a matching certified intrinsic safety barrier inside the local enclosure to restrict loop energy under fault conditions.

Q: What output behavior occurs at the monitor rack if the ClickLoc connector unlatches while the monitoring loop is live?

A: An unlatched connector forces an open-circuit state across the proximity circuit loop. The Proximitor sensor detects this anomaly, drives its voltage output to maximum saturation, and forces the associated monitor card to trigger a NOT OK fault status to suppress false trip execution.

Field Installation Guidelines

• Connection Engagement: Push the male and female miniature ClickLoc connectors together firmly until an audible click confirms positive mechanical engagement. Do not use pliers or aggressive tools to tighten the coaxial interfaces.

• Cable Bend Path Limitations: Maintain a minimum bend radius of 25.4 mm (1.0 inch) along all segments of the 4.0-meter coaxial cable run. Sharp kinks or compressed routing paths degrade insulation layers and compromise shielding performance.

• Shielding Separation Requirements: The exposed metal parts of the ClickLoc connectors must remain isolated from any contact with the machine chassis, structural conduits, or oil barriers. Use insulated junction boxes or silicone sleeves to maintain a single-point grounding layout at the monitor rack.

• Moisture Prevention: Ensure the connector junction inside the local housing is completely dry and free of oil or water contamination before mating, as moisture ingress shifts the high-frequency line impedance and induces false vibration signals.
