The Bently Nevada 330130-085-00-CN, also cataloged as the 330130 Standard Extension Cable, operates as a dedicated hardware component for high-frequency RF signal transmission within 3300 XL Proximity Transducer System loops.

Suffix Nomenclature

• 085: 8.5 meters (27.9 feet) physical cable length configuration

• 00: Standard cable option without integrated connector protectors

• CN: CSA, ATEX, and IECEx hazardous area structural approvals

Hardware Specifications

Eddy-Current Probe Scaling and Rotor Dynamics

The extension cable functions as a calibrated electrical parameter block matching the RF impedance requirements of the 3300 XL proximity sensor driver. It maintains a stable capacitance distribution profile across its 8.5 meters path to preserve eddy-current probe scaling line slopes. This stabilization allows precise tracking of target displacements during dynamic rotor dynamics shifts. The internal physical design isolates low-level displacement voltages from stray noise fields to secure cross-talk suppression between parallel proximity loops, ensuring accurate gap voltage validation against standardized -10 VDC target baselines.

Field Installation Guidelines

Route the extension cable inside a dedicated, clean, grounded metal conduit to isolate the RF path from mechanical shear forces and external electromagnetic interference. When layout boundaries dictate direction changes, observe a minimum bend radius limit to avoid crushing the internal dialectic layers and changing the nominal 50 Ohms impedance profile. Ensure all miniature coaxial connections are torqued finger-tight and sealed with clean, dry insulation sleeves to prevent fluid ingress. Do not shorten or alter the physical length of the cable, as changing the 8.5 meters tuning metrics will invalidate the calibration of the matched Proximitor sensor.

Shipment Information

Delivery time: 2-7 days when payment finish parameters are documented. All items ship internationally from Xiamen, China via global air networks including DHL, FEDEX, and UPS. Hardened industrial components are individually secured within multi-layer anti-static industrial packaging configurations to maintain complete insulation integrity during continental or transoceanic transport.

Frequently Asked Questions

Q: How does a deviation from the typical 69.9 pF/m cable capacitance alter system operation?

A: The Proximitor driver utilizes the specific inductive and capacitive properties of the transmission path to linearize the displacement output. Deviations from the nominal capacitance distort the eddy-current probe scaling, inducing measurement errors across the target gap tracking range.

Q: Can an 8.5 meters extension cable be combined with different 3300 XL probe lengths?

A: The cumulative electrical length of the proximity probe plus the extension cable must match the total system length specification printed on the Proximitor label. Mixing mismatched length elements disrupts the tuned RF resonant loop, causing gap voltage validation failures.

Q: What are the engineering consequences of moisture accumulation inside the coaxial connectors?

A: Liquid or oil contamination at the connector interface introduces parallel resistance paths. This path drops the insulation index, degrades cross-talk suppression metrics, and shifts the dynamic voltage readings, which can mimic artificial rotor dynamics trends or cause loop faults.
