Features:

  • Interface Between the 84661‑70 Interconnect Cable and Bently Nevada Monitoring Systems
  • Combines Capability of 84661-70 Cable with High-Temperature FluidLoc Armor Protection
  • Operates in Conjunction with 3300, 3500, and Other Standard Bently Nevada Monitors
The 84661‑70 operates as a high-integrity interconnect cable within Bently Nevada monitoring systems, providing reliable signal transmission between proximity, vibration, and seismic sensors and 3300/3500 monitors. It continuously carries sensor signals over shielded, armored conductors, ensuring accurate, real-time data delivery for condition monitoring and machine protection. The cable’s robust shielding, corrosion-resistant connectors, and industrial-grade insulation provide dependable operation even in harsh environments with high electromagnetic interference, moisture, or temperature extremes. The 84661‑70 has made improvements over previous interconnect cable designs, including enhanced signal stability, extended mechanical durability, and universal compatibility across multiple Bently Nevada probes and monitoring modules.

The 84661‑70 provides essential signal transmission functions for Bently Nevada monitoring systems, and is a critical component of the condition monitoring path, directly affecting the accurate, reliable operation of all connected sensors and monitors. One or more 84661‑70 cables may be required per machine depending on the number of sensors and desired monitoring coverage. The 84661‑70 features a shielded, armored design with corrosion-resistant connectors and is installed in dedicated sensor locations, ensuring stable signal acquisition and seamless integration with 3300, 3500, and other Bently Nevada monitoring modules.

For Dual Redundant Sensor Cable applications, the 84661‑70 may be installed in a secondary or redundant monitoring channel to ensure uninterrupted signal transmission. In addition to standard single-cable operation, the redundant configuration can perform automatic switchover. The dual-cable configuration executes failover using internal signal verification built into the 3300/3500 monitoring systems. Using this method, the redundant cable setup continually monitors the integrity of both cables. If the system detects that the primary cable is no longer providing stable sensor signals (outside configured tolerance levels), it will automatically transfer monitoring functions to the secondary cable and log an event in the system diagnostics and event history.

The 84661-70 Bently Nevada Interconnect Cable may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
