Bently Nevada Velomitor Piezo-velocity Sensors are designedto measure absolute (relative to free space) bearing housing,casing, or structural vibration. The 330500 is a specializedpiezoelectric accelerometer that incorporates embeddedintegrated electronics in a solid-state design.
Because the 330500 incorporates solid-state electronics andhas no moving parts, it does not suffer from mechanicaldegradation and wear, and can be mounted vertically,horizontally, or at any other angle of orientation.
Most common machine malfunctions (unbalance,misalignment, etc.) occur on the rotor andoriginate as an increase (or at least a change) inrotor vibration. For any individual casingmeasurement to be effective for overall machineprotection, the system must continually transmit asignificant amount of rotor vibration to themachine casing, or mounting location of the
transducer.
In addition, be careful to install the accelerometertransducer on the bearing housing or machinecasing. Improper installation may decrease thetransducer amplitude and frequency responseand/or generate false signals that do not representactual vibration. Refer to the appropriate instructionmanuals and Application Notes.
Upon request, Bently Nevada provides engineeringservices that can identify the appropriate machine housing measurements andinstallation assistance if needed.
