Bently 3500/45(also often written as Bently Nevada 3500/45)is a position monitor or differential expansion monitor produced by Bently Nevada.The following is a detailed introduction to it:
I.Product Overview
Bently 3500/45 is a four-channel device that can obtain data from a variety of sensors,including proximity sensors,rotary position sensors(RPTs),DC linear variable differential transformers(DC LVDTs),AC linear variable differential transformers(AC LVDTs),and rotary potentiometers.The monitor pre-processes the signal and compares it with user-programmable alarms to trigger alarms to protect the machine.
II.Main functions
Versatility:
The 3500/45 has multiple functions such as differential expansion,compensated input differential expansion,and housing expansion,which can be selected and programmed according to actual needs.
Signal stability:
Using displacement input/output modules,it can receive input signals from a variety of sensors to ensure signal stability and accuracy.
Alarm function:
The alarm is driven by continuously comparing the rotor displacement at the time with the alarm set point,and the alarm is issued in time to ensure the safety of the equipment.
Easy to program:
Programming is done using the 3500 rack configuration software,which is easy to operate,maintain and upgrade.
High reliability:
Made with high-quality materials and processes,it has high reliability and stability,and can ensure long-term stable operation.
