<Vibration/Displacement Monitor Module (VM-701)>
The Vibration/Displacement Monitor Module is a monitor that monitors the vibration level and
position of the shaft of rotating machineries, and thermal expansion difference between the rotor
and casing.
This module provides functions for measuring various type vibration and displacement of rotating
machineries through software and hardware settings, and is compatible with up to four channel
inputs.
Also, this module provide the recorder output corresponding to input signals and contact output, to
outside equipment via the rear panel of the instrument rack.
