Where It Excels in Industrial Use

• Armored Velocity Sensor Interconnect
The Bently Nevada 84661-26 Velomitor Interconnect Cable is designed for reliable signal connection between Bently Nevada Velomitor velocity sensors and machinery monitoring systems. It is part of the 84661 armored cable family, providing enhanced mechanical protection compared with standard unarmored interconnect cables.

• Rotating Machinery Vibration Monitoring
The cable is used in vibration monitoring applications for critical rotating equipment such as turbines, compressors, pumps, motors, and generators, where stable velocity signal transmission is required for machinery protection and predictive maintenance.

• Harsh Industrial Installations
The armored construction helps protect the cable against abrasion and mechanical damage, while the shielded design reduces susceptibility to electromagnetic interference in industrial environments.

• Flexible Medium-Length Installations
The 26 ft (approximately 7.9 m) cable length provides additional routing flexibility between a field-mounted Velomitor sensor and the monitoring cabinet. The "-26" suffix identifies the cable length option in feet.
