Configured for signal transmission in vibration monitoring architectures, the Bently Nevada 16929-12 (16929-12 Interconnect Cable) provides physical electrical connectivity for transducer signal pathways within 3300 series systems.

Cable Physical Configuration

• Model: 16929-12
• Function: Interconnect Cable
• Insulation: Standard (High-temp option available)
• Standard Length: Variable (1 m to 30 m)

Hardware Specifications

Mechanical Monitoring & TSI Properties

The cable assembly facilitates eddy-current probe scaling by maintaining signal integrity between the transducer and the Proximitor sensor. Performance is dependent on maintaining precise impedance characteristics to ensure gap voltage validation at -10 VDC targets. Routing must prioritize cross-talk suppression by separating signal lines from high-frequency interference sources, thereby maintaining the accuracy of rotor dynamics measurements recorded by the monitoring system.

Field Installation Guidelines

• Routing: Install within shielded conduits to minimize electromagnetic noise and prevent physical damage to the coaxial sheath.
• Bend Radius: Adhere to minimum bend radius specifications to avoid deformation of the coaxial core and ensure constant impedance.
• Connections: Confirm mechanical seating of connectors; hand-tighten to ensure firm contact without over-torquing the interface.
• Environment: Ensure cable temperature ratings align with ambient conditions, utilizing high-temperature variations if routed near thermal zones.

Frequently Asked Questions

• Can this cable be used with non-Bently Nevada transducers? This cable is designed specifically for Bently Nevada 3300 series impedance characteristics; performance with third-party transducers is not supported.
• What is the significance of the 100 pF/m capacitance limit? Lower capacitance is necessary to minimize signal attenuation and phase shift over long cable runs, ensuring high-frequency vibration data remains accurate.
• Is this cable compatible with hazardous area installations? Verify the installation control drawings, as hazardous area compliance is contingent upon the entire loop configuration rather than the cable alone.
• How does the 300 V AC/DC rating apply? This rating defines the maximum electrical insulation threshold; signal levels for vibration monitoring are typically much lower.
• Can the cable be cut to a specific length? System impedance is calibrated based on total length; cutting the cable will alter electrical characteristics and require system-wide recalibration.
• What material is used for the insulation? Standard cables utilize industry-standard insulation, while high-temperature options incorporate FEP or PFA for enhanced thermal resilience up to 200 deg C.
• Does the cable require a specific termination tool? Standard coaxial connectors can be mated manually; ensure the contact surfaces are clean and free of conductive debris before engagement.
• How is cross-talk minimized in multi-cable installations? Maintain physical separation between signal cables and ensure all shields are grounded at the designated common point within the system cabinet.
