Where It Excels in Industrial Use

• Armored Velocity Sensor Interconnect
The Bently Nevada 84661-40 Velomitor Interconnect Cable is designed to connect Bently Nevada Velomitor piezo-velocity sensors to vibration monitoring systems. It provides a rugged, shielded signal connection for industrial machinery condition monitoring applications.

• Critical Rotating Machinery Monitoring
The cable is used with rotating equipment such as turbines, compressors, pumps, motors, and generators where reliable velocity vibration signals are required for machinery protection and predictive maintenance.

• Harsh Industrial Environments
The 84661 series uses an armored construction with shielded conductors, providing improved protection against abrasion, mechanical stress, and electrical interference. The cable family is specified as a flexible stainless-steel armored version of the standard 9571 shielded cable.

• Extended Sensor-to-Monitor Installation
The “-40” suffix indicates a 40 ft (approximately 12.2 m) cable length, providing additional routing distance between field-mounted Velomitor sensors and monitoring cabinets.
