Bently Nevada 9571-20 Standard Interconnect Cable

Configured for high-fidelity vibration signal transmission in 3500 and 3300 monitoring architectures, the Bently Nevada 9571-20 (9571 Standard Interconnect Cable) provides direct physical/electrical execution.

Suffix Breakdown & Model Matrix

• 9571: Model designation for low-cost standard accelerometer interconnect cable assembly
• -20: Cable Length Option (20 feet / 6.1 meters)
• 2-Socket Female: Transducer-end sealed moisture-resistant connector
• Terminal Lugs: Monitor-end pre-terminated ring lugs

Hardware Specifications

Rotor Dynamics and Eddy-Current Probe Scaling

Interconnect cabling for accelerometers and dynamic pressure transducers maintains signal purity across long distances between machine casings and monitoring racks. The 2-conductor twisted pair design with overall aluminum foil shielding suppresses high-frequency electromagnetic interference (EMI) and radio frequency interference (RFI) generated by rotating electrical machinery. Maintaining low-impedance shield continuity prevents signal cross-talk suppression degradation, preserving accurate rotor dynamics and phase-tracking data sent to 3500 series vibration cards.

Frequently Asked Questions

Q: Can the 9571-20 cable be trimmed to a shorter custom length during field installation?

A: Yes. The monitor end uses standard terminal lugs; the cable can be cut, stripped, and re-terminated with crimp lugs provided the shield drain wire is properly preserved.

Q: Is the 2-socket female connector suitable for wet or outdoor plant environments?

A: Yes. The 2-socket sensor connector features an internal moisture-resistant seal, though severe outdoor deployments should utilize additional protective boots or junction enclosures.

Field Installation Guidelines

• Inspect the 2-socket female connector boots and pins prior to installation to ensure no physical contamination or bent pins exist.
• Thread the 2-socket female connector firmly onto the accelerometer housing socket, hand-tightening the coupling nut to ensure a moisture-sealed connection.
• Route the cable along panel ducting or rigid conduit, maintaining a minimum bend radius of 30 mm (1.2 inches) to avoid copper conductor fatigue.
• Connect the pre-wired terminal lugs to the monitor rack or field junction box terminal strip, observing correct signal polarity (Signal/A and Common/B).
• Terminate the shield drain wire exclusively at the monitor end ground bus bar, keeping the sensor-end shield ungrounded to prevent ground loops.
