The Bently Nevada 16710-20, also cataloged as the 16710-20 Interconnect Cable, operates as a dedicated hardware component for signal transmission between 330400/330425 accelerometers and monitoring platforms. This 3-conductor shielded cable provides the physical pathway for acceleration signals, ensuring high-frequency vibration data is transmitted with low signal degradation and noise immunity. The assembly is engineered to maintain electrical continuity between the transducer end and the terminal block of the monitoring system.

Cable Configuration & Matrix

• 16710: Base model for accelerometer interconnect cables.

• 20: Standard length option (20 feet / 6.1 meters).

Hardware Specifications

Signal Integrity and Cross-Talk Suppression

In acceleration monitoring, the integrity of the transmission path is critical to rotor dynamics analysis. The 16710-20 utilizes a 3-conductor shielded architecture to facilitate effective cross-talk suppression and mitigate electromagnetic interference in industrial environments. Proper shield termination at the monitoring system input is necessary to provide a stable reference and avoid ground loops that introduce electrical noise. By strictly maintaining rated capacitance and impedance characteristics, this cable ensures that low-level vibration signals remain clear of extraneous frequency components, allowing for precise identification of mechanical fault signatures.

Field Installation Guidelines

• Cable Routing and Strain Relief

• Route the cable through dedicated metallic conduit to provide shielding and prevent mechanical damage from abrasion or fluid contact.

• Observe a minimum bend radius to avoid damaging the internal conductors and dielectric insulation.

• Use appropriate strain relief clamps to secure the cable at the transducer housing and entry points into monitoring enclosures.

• Termination Practices

• Connect the 3-socket plug securely to the accelerometer interface until fully seated.

• Terminate the wire lugs to the input terminal blocks of the monitor, ensuring a clean, low-resistance connection to the signal common and signal positive terminals.

Frequently Asked Questions

• Is the cable length field-modifiable?

  The cable is factory-calibrated for specific impedance and capacitance. Cutting or extending the length will alter these electrical properties and impact signal accuracy.

• What does the 3-conductor configuration include?

  The configuration typically includes signal positive, signal common, and shield conductors required to support the accelerometer's power and data transmission.

• Is the cable shielding grounded at both ends?

  Grounding practices should follow the specific monitor manual; typically, the shield is grounded at the monitoring system end only to prevent ground loop currents.

• What materials are used for the outer jacket?

  The cable utilizes fluoroethylenepropylene (FEP) insulation, which offers chemical resistance to hydrocarbons and durability in high-temperature environments.

• Can this cable be used for proximity probe applications?

  No, this cable is specifically designed for accelerometer transducer systems and is not compatible with the impedance requirements of eddy-current proximity probes.

• What is the tensile strength of the cable?

  The maximum tensile strength between the probe case and the probe lead is 222 N (50 lbf). Avoid applying excessive tension during installation or operation.

• How should the connector be protected during installation?

  Keep the connector capped and free of dust or moisture until the moment of mating to ensure a high-integrity electrical contact.

• Can the cable be used in hazardous areas?

  The suitability for hazardous areas is defined by the overall system certification; ensure the installation complies with local safety standards and system documentation.
