Bently Nevada 330190 Series Technical Notes

The Bently Nevada 330190 series comprises armored extension cables engineered for use with 3300 XL 8mm proximity transducer systems. These cables serve as the signal-transmission link between the proximity probe and the proximitor/driver module, operating in environments where mechanical vibration, shaft displacement, and axial position monitoring are mission-critical. The 330190 series is installed across heavy industrial sectors including petrochemical refineries, nuclear power stations, offshore platforms, LNG terminals, and rotating machinery trains in steel mills. Its field-proven design supports continuous operation under high-temperature, high-vibration, and chemically aggressive ambient conditions. The series is fully compatible with Bently Nevada 3300 XL, 3500, and 7200 series monitoring systems, making it one of the most widely deployed extension cable families in the global condition monitoring market.

330190 Full Catalog & Functionalities (SKU List)

The following part numbers represent the verified 330190 series catalog, organized by cable length. Each SKU is a complete, factory-terminated extension cable assembly for 8mm proximity probe systems.

330190-085-00-00: 0.85 m armored extension cable, 8mm probe, TNC connectors, standard temperature rating.
330190-090-00-00: 0.90 m armored extension cable, compatible with 3300 XL and 3500 proximitor inputs.
330190-100-00-00: 1.00 m standard-length extension cable, most common replacement length for turbine bearing housings.
330190-150-00-00: 1.50 m extension cable, used where probe-to-proximitor routing requires additional slack.
330190-175-00-00: 1.75 m armored cable assembly, suited for mid-distance routing in compressor trains.
330190-200-00-00: 2.00 m extension cable, standard for larger bearing pedestals and gearbox applications.
330190-250-00-00: 2.50 m cable, used in applications with extended conduit runs between probe and junction box.
330190-300-00-00: 3.00 m extension cable, common in large steam turbine installations with remote proximitor mounting.
330190-350-00-00: 3.50 m armored assembly, used in offshore and marine turbomachinery with separated monitoring panels.
330190-400-00-00: 4.00 m extension cable, supports long-run installations in power generation and refinery applications.
330190-450-00-00: 4.50 m cable assembly, used in large-frame gas turbines with remote rack mounting.
330190-500-00-00: 5.00 m extension cable, maximum standard length for most 3300 XL system configurations.
330190-600-00-00: 6.00 m extended-run cable, used with 3500 series systems where rack distance exceeds standard limits.
330190-750-00-00: 7.50 m long-run armored cable, requires system gap voltage verification at installation.
330190-900-00-00: 9.00 m maximum-length assembly, used in large power plant installations with centralized monitoring rooms.
330190-085-00-CN: 0.85 m cable, China-market variant with localized connector labeling.
330190-100-00-CN: 1.00 m cable, China-market variant, functionally identical to standard -00-00 suffix.

Quality Control for the 330190 Range

Extension cables in the 330190 series are passive assemblies, but their electrical characteristics — cable capacitance, shield continuity, connector contact resistance, and armor integrity — directly affect proximity system accuracy. DriveKNMS applies the following inspection protocol to all 330190 units: (1) Visual inspection of armor jacket for kinks, crush damage, and connector body corrosion. (2) Continuity and insulation resistance test on center conductor and shield. (3) Capacitance measurement per unit length, verified against Bently Nevada specification (typically 98–102 pF/m for standard 330190 cable). (4) Connector mating force and thread engagement check on both TNC-style terminations. (5) Full-system functional test when paired with a 330180 8mm probe and 3300 XL proximitor, confirming gap voltage output within ±0.1 VDC of specification at a calibrated target distance. Units that fail any parameter are quarantined and not listed for sale.
