Bently Nevada Velomitor Series Technical Notes

The Bently Nevada Velomitor series is a velocity transducer platform engineered for continuous vibration monitoring in heavy industrial environments including petrochemical refineries, nuclear power stations, offshore platforms, and rotating machinery installations. Deployed across thousands of turbomachinery trains globally, the Velomitor product line integrates directly with Bently Nevada 3500 Series rack-based monitoring systems and legacy 7200 Series frameworks. Its piezoelectric velocity output (ICP®-compatible) and rugged stainless-steel housing make it the reference standard for bearing housing vibration measurement in API 670-compliant installations. The 84661-90 is a factory-terminated interconnect cable assembly used to link Velomitor transducers to field junction boxes or monitor input terminals, maintaining signal integrity across the full operating temperature range.
