Bently Nevada Velomitor Piezo-velocity Sensors are designed to measure absolute (relative to free space) bearing housing, casing, or structural vibration. The 330500-02-05 is a specialized piezoelectric accelerometer that incorporates embedded integrated electronics in a solid-state design.
Because the 330500-02-05 incorporates solid-state electronics and has no moving parts, it does not suffer from mechanical degradation 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 and
originate as an increase (or at least a change) in
rotor vibration. For any individual casing
measurement to be effective for overall machine
protection, the system must continually transmit a
significant amount of rotor vibration to the
machine casing, or mounting location of the
transducer.
In addition, be careful to install the accelerometer
transducer on the bearing housing or machine
casing. Improper installation may decrease the
transducer amplitude and frequency response
and/or generate false signals that do not represent
actual vibration. Refer to the appropriate instruction
manuals and Application Notes.
Upon request, Bently Nevada provides engineering
services that can identify the appropriate machine.
