The Bently Nevada 330500 Velomitor measures absolute (relative to free space) bearing housing, casing, or structural vibration. Unlike moving-coil velocity transducers, such as the Bently Nevada Seismoprobe family of velocity transducers, Velomitor Piezo-velocity sensors are specialized piezoelectric accelerometers that incorporate embedded integrated electronics in a solid-state design. Because they incorporate solid-state electronics and have no moving parts, they do not suffer from mechanical degradation and wear, and can be mounted vertically, horizontally, or at any other angle of orientation.
