BENTLY 3500/42M 140734-02 is a high-performance vibration and position monitoring module,which belongs to the Bently Nevada 3500 series and is widely used in mechanical protection and condition monitoring of industrial equipment.The following is a comprehensive analysis of its core functions and technical parameters:
I.Core functions
Multi-channel signal processing
-Four-channel design:supports simultaneous monitoring of four independent signals,and each channel can be independently programmed and configured.
-Sensor compatibility:can receive displacement,velocity,acceleration sensor input,suitable for different types of vibration and position measurement.
Flexible measurement function
-Through the programming of 3500 framework configuration software,more than 10 measurement functions such as radial vibration,axial displacement,differential expansion,eccentricity,REBAM®(rotating machinery fault diagnosis)can be realized.
-Channel pair programming,up to two functions can be completed at the same time(such as channels 1-2 for radial vibration,channels 3-4 for axial displacement).
Alarm and protection
-Continuously compare the actual vibration value with the alarm threshold set by the user,trigger an alarm or protection action(such as shutdown)to ensure equipment safety.
-The front panel LED indicator shows the module operating status(such as OK light,communication status,etc.),assisting fault diagnosis.
II.Technical parameters
