Bently Nevada 330980-71-CN – Interconnecting Cable for 3500/3300 XL Vibration Monitoring

The 330980-71-CN appears to be a Bently Nevada interconnecting cable used around the 3500/3300 XL condition monitoring system—typically for routing low-level vibration or proximity transducer signals between proximitor/sensor interfaces and the rack I/O. From my experience, this series focuses on noise immunity, reliable factory terminations, and consistent performance in demanding industrial panels.

Key Features

• Designed for Bently Nevada 3500/3300 XL environments – Commonly used to link proximitor/sensor interfaces to 3500 rack I/O or terminal strips.
• Low-noise signal routing – Shielded construction helps preserve accuracy of low-level vibration and proximity signals over cabinet runs.
• Factory-terminated ends – Typically supplied with matched connectors/lead terminations for faster, cleaner installation.
• Industrial-grade jacket – Durable insulation suitable for control cabinets and plant panel ducting; in many cases resistant to oils and common solvents.
• Traceability – Clear labeling and length code simplify maintenance and future modifications.
• Compatibility-focused – Intended to maintain impedance and shielding practices Bently Nevada specifies for stable measurements.

Technical Specifications

Application Fields

Facilities that rely on Bently Nevada 3500/3300 XL monitoring—oil & gas (compressors, pumps), power generation (turbines, generators), petrochemical rotating assets, steel mills, paper machines, and large HVAC chillers. You might notice that many teams use this cable type when standardizing panel wiring to keep vibration data stable and repeatable across units.

A maintenance lead from a refinery shared with us that swapping in factory-terminated interconnects cut their panel rework by half during a 3500 upgrade—less time tracing shields, fewer noise-related alarms during commissioning.

Advantages & Value

• Reliability – Shielded, purpose-built cable helps maintain signal integrity for trending and protection trips.
• Compatibility – Spec’d for common Bently Nevada proximitor/monitor terminations; reduces mismatches that cause nuisance alarms.
• Cost control – Factory terminations and consistent pinouts typically shorten installation and loop-check time.
• Technical support – We can share wiring diagrams, shield grounding guidance, and mounting tips specific to your 3500 cabinet layout.

Installation & Maintenance

• Cabinet environment – Route in grounded metal duct where possible, away from VFD power cables. Keep bend radius ≥10× cable OD.
• Shielding practice – Follow Bently Nevada guidelines; in many cases, shields are grounded at one end only to avoid ground loops.
• Terminations – Torque terminal screws per the device manual; avoid over-stripping conductors. Label both ends to match the channel map.
• Routine checks – Inspect jacket for abrasion/chemical exposure quarterly; verify continuity and shielding if noise increases.
• Firmware/Calibration – The cable itself needs no firmware; however, it’s good practice to verify monitor channel calibration after any cable swap.
• Ventilation – Maintain cabinet airflow. Elevated temperatures degrade cable jackets over time, especially near power supplies.

Quality & Certifications

• Typically compliant with CE and RoHS for cabling used in industrial panels
• UL AWM style or similar may apply depending on the exact build; documentation available on request
• Manufacturer warranty support aligned with a 365-day coverage from our side

Helpful note: If you can share your 3500 monitor module types (e.g., 3500/40M, 3500/42M) and proximitor/probe part numbers, we’ll confirm pinouts and the exact “-71” length mapping for 330980-71-CN before shipment. That small step typically avoids commissioning delays.
