Where It Excels in Industrial Use

• Armored Velocity Sensor Interconnect Cable
The Bently Nevada 84661-67 Velomitor Interconnect Cable is designed to connect Bently Nevada Velomitor piezo-velocity sensors to vibration monitoring systems. It provides a protected signal path for accurate velocity vibration measurement on critical rotating machinery.

• Long-Distance Machinery Monitoring Installations
The “-67” suffix identifies a 67 ft (approximately 20.4 m) cable length, providing extended routing capability between field-mounted Velomitor sensors and monitoring cabinets.

• Industrial Rotating Equipment Applications
The cable is used in vibration monitoring systems for equipment such as:

• Steam turbines
• Gas turbines
• Compressors
• Pumps
• Motors
• Generators

It supports machinery condition monitoring and protection systems where reliable velocity signal transmission is required.

• Harsh Environment Protection
The 84661 series uses an armored construction over shielded conductors, providing improved resistance against abrasion and mechanical damage while maintaining signal integrity in industrial environments.
