190501-12-00-00 Bently Nevada Velomitor CT Velocity Transducer Description Th e Bently Nevada190501-12-00-00 is a piezoelectric velocity sensor, marketed under the “Velomitor CT” family. It is explicitly designed as a low-frequency version of Bently’s standard Velomitor velocity sensor, so that it can effectively measure vibration on slower-speed machinery (for example cooling towers, air-cooled heat-exchanger fans)operating at around 90 rpm and upward. The typical use case:
