Bently Nevada 9571-10 Two-Conductor Twisted Shielded Interconnect Cable

The 9571 instrumentation interconnect cable, complete part number 9571-10, is a high-performance two-conductor 22 AWG shielded cable assembly designed for transmitting dynamic vibration signals within machinery protection systems. The physical construction features a moisture-resistant two-socket female connector at the sensor termination end to maintain electrical insulation in humid environments, while the monitor termination end is fitted with standard terminal lugs for robust installation into I/O chassis backplanes. This 10 ft (3.05 m) twisted-pair configuration provides superior differential noise rejection, ensuring precise signal transmission from compatible transducers directly to Bently Nevada machinery monitors. This cable is explicitly not designed for integration within the 21128 Velocity Transducer Housing.

Hardware Specifications

Engineering Notes

• The 22 AWG twisted-pair geometry provides high noise immunity against electro-magnetic interference by canceling out differential-mode noise along the signal pathway.
• The sensor-end termination utilizes a specialized moisture-resistant compound within the 2-socket female connector housing to prevent moisture ingress from degrading insulation resistance.
• Total loop resistance and cable capacitance scale linearly with length; ensure overall parameters align with monitoring system input barriers to maintain accurate high-frequency data transfer.

Field Guidelines

• Connect the cable shield drain wire exclusively to the instrument rack instrumentation ground bar, and completely isolate the shield at the transducer end to prevent structural ground loops.
• Route the signal cable away from high-voltage AC electric motor supply cables, variable frequency drives (VFDs), and heavy inductive switching elements to maintain raw signal integrity.
• Adhere strictly to industrial minimum bending radius standards during conduit routing to prevent physical degradation of the internal shield foil and 22 AWG copper strands.
• Ensure the moisture-resistant connector is fully locked and sealed against the sensor body to guarantee long-term environmental protection and reliable contact interface.
