Bently Nevada 3500/45 | Differential Expansion/Axial Position Monitor

The name of Bently Nevada 3500/45 is Differential Expansion/Axial Position Monitor.

· Number of channels: It is a 4-channel monitor.

· Input signal types: Can receive input signals from proximity eddy current sensors, rotary position sensors (RPT), DC linear variable differential converters (DCLVDT), AC linear 

variable differential converters (AC LVDT), and rotary potentiometers.

· Working voltage: usually 24VDC.

· Size: Half height module, can be installed in 3500 series racks.

· Mechanical protection: By continuously comparing the rotor displacement at that time with the alarm set point to drive the alarm, when the monitored rotor displacement 

exceeds the set alarm value or danger value, an alarm signal will be promptly issued to remind the operator to take measures to prevent equipment damage caused by 

abnormal rotor displacement, such as bearing wear, shaft misalignment, friction between moving and stationary components, and other faults.

· Monitoring differential expansion and casing expansion: Using the 3500 framework configuration software to program the 3500/45, monitoring functions such as differential 

expansion, compensating input differential expansion, and casing expansion (CH3, CH4) can be executed to ensure that the thermal expansion and contraction of the 

equipment during operation are within normal ranges. For large rotating equipment such as steam turbines, compressors, etc., it can effectively monitor the expansion 

changes of key parts and ensure the safe and stable operation of the equipment.
