Bently Nevada 84661-20 Velomitor Interconnect Cable

The Bently Nevada 84661-20 is a specialized industrial signal cable designed specifically for use with the Velomitor series of piezoelectric velocity sensors. This 20-foot (6.1-meter) assembly facilitates the transmission of low-amplitude vibration signals from the sensor mounted on the machine casing to the monitoring instrumentation. By utilizing a shielded twisted-pair architecture, the cable effectively suppresses electromagnetic noise, ensuring that the dynamic velocity data remains accurate for machinery protection and diagnostic analysis.
