BENTLY 3500/42M 140734-02 is a four-channel monitoring module produced by Bently,mainly used for vibration and position measurement.The following is a detailed introduction to the module:
I.Product Overview
BENTLY 3500/42M 140734-02 is a high-performance four-channel monitor that can receive signals from displacement,velocity,and acceleration sensors,and complete various vibration and displacement measurements by processing these signals.At the same time,it can also compare the processed signals with the alarm set points programmed by the user,provide mechanical protection,and return status values.

II.Main functions
Multi-channel monitoring:The module has four independent monitoring channels,each of which can receive signals from different types of sensors,such as displacement,velocity,acceleration sensors,etc.
Vibration and displacement measurement:It can accurately measure the vibration and displacement parameters of mechanical equipment,including radial vibration,axial displacement,differential expansion,shaft eccentricity,etc.
User programmability:Users can program the module through the 3500 framework configuration software to set alarm values,measurement parameters,etc.to meet different monitoring needs.
Mechanical protection:The monitor will compare the signal with the alarm point set by the user.Once the set value is exceeded,the alarm system will be triggered to achieve mechanical protection.
Status return:The monitor also returns the status valuesof the monitor and the channel,including hardware failure,sensor failure,etc.,to facilitate users to perform fault diagnosis and maintenance.
