Where It Excels in Industrial Use

• Armored Velocity Sensor Interconnect
The Bently Nevada 84661-30 Velomitor Interconnect Cable is designed for connecting Bently Nevada Velomitor piezo-velocity sensors to compatible vibration monitoring systems. It provides a rugged signal path for industrial machinery monitoring applications where mechanical protection and signal integrity are important.

• Critical Rotating Machinery Monitoring
The cable is commonly applied in vibration monitoring systems for turbines, compressors, pumps, motors, generators, and other rotating machinery requiring reliable velocity measurement for condition monitoring and machinery protection.

• Harsh Industrial Environments
Its armored construction protects the cable from abrasion and mechanical stress, while the shielded twisted-pair design helps reduce electromagnetic interference and preserve vibration signal quality.

• Medium-Distance Field Installations
The 30 ft (9.1 m) cable length provides practical routing flexibility between field-installed Velomitor sensors and monitoring equipment. The "-30" suffix identifies the cable length option in feet.
