Technical Summary

The Bently Nevada CB2W100-064 is a 64 feet (19.5 meters) interconnect cable engineered for transmitting dynamic vibration and acceleration signals within machinery protection systems. It establishes a secure, low-noise signal path between industrial transducers and monitoring mainframes, minimizing electromagnetic interference (EMI) and preventing signal attenuation or false trips. The cable utilizes a twisted-pair architecture with a dedicated shield to maintain signal integrity over long-distance runs in harsh electromagnetic environments.

Technical Configuration

• CB2W100: Product series designation for premium, high-temperature dynamic signal interconnect cables.
• -064: Specifies the exact physical length of the cable assemble, designated as 64 feet (equivalent to 19.5 meters).
• Connectors: Features a MIL-C 5015 standard 2-socket connector at the sensor end with splash-proof isolation, transitioning to a blunt-cut termination at the monitor/junction box end.
• Conductors: 20 AWG twisted pair copper conductors optimized for low electrical resistance and high tensile strength.
• Shielding: Integrated braided or foil shield providing continuous coverage against radio frequency and electrostatic noise.
• Jacket Material: High-durability yellow Teflon (FEP) insulation offering superior chemical resistance and thermal stability.

Engineering FAQs

Q: How should the shield wire of the CB2W100-064 be terminated to avoid ground loops?

The shield must be grounded at one single point, typically at the monitor rack or structural ground inside the junction box. Leave the shield floating and isolated at the transducer end using the premium isolated MIL-C 5015 connector housing to prevent circulating ground currents from corrupting the vibration signal.

Q: Can this cable be used with proximity probe systems or is it strictly for accelerometers?

This 2-socket MIL-C 5015 configuration is primarily designed for 2-wire accelerometers and velocity sensors. Standard proximity probes require 3-wire extension cables (such as the 3300 XL series). Verify transducer pinning before deployment.

Q: What is the maximum temperature rating for the yellow Teflon jacket?

The Teflon (FEP) jacket is rated for continuous operation from -55 to +200 deg C, making it suitable for routing near hot casing surfaces on steam turbines, gas turbines, and compressors.

Field Guidelines

1. Maintain a minimum bend radius of 75 mm during installation to prevent internal conductor fatigue or damage to the Teflon insulation layer.
2. Route the cable through dedicated, grounded metal conduit when deploying across open structural spans to provide mechanical protection and secondary EMI shielding.
3. Secure the MIL-C 5015 threaded connector to the sensor housing using a calibrated torque wrench, ensuring the splash-proof seal is fully compressed without over-tightening.
4. Keep the interconnect cable isolated from high-voltage AC power lines by a minimum clearance of 300 mm to eliminate cross-talk and induction noise on the low-voltage AC/DC vibration signal.
