Bently NevadatM Velomitor Piezo-velocity Sensors aredesigned to measure absolute (relative to free space)bearing housing, casing, or structural vibration. The 330500 isa specialized piezoelectric accelerometer that incorporatesembedded integrated electronics in a solid-state design.

Because the 330500 incorporates solid-state electronics and has no moving parts, it does not suffer from mechanicaldegradation and wear, and can be mounted vertically, horizontally, or at any other angle of orientation
