Bently Nevada 1900/65 Equipment Monitor

The Bently Nevada 1900/65 monitor delivers continuous protection and condition monitoring for plant equipment across Oil & Gas, Power Generation, Mining, Water Treatment, and other heavy-industry environments. The 1900 series design supports eight sensor inputs, multiple alarm outputs, and flexible installation options that suit both new machinery packages and retrofit projects.

Product Overview

Engineers rely on the 1900/65 because it processes vibration and temperature data simultaneously, and it drives clear alert and danger alarms for every monitored variable. The system also offers buffered outputs that simplify diagnostic work, while the optional remote display improves visibility across large installations.

System Capabilities

The 1900/65 combines vibration and temperature monitoring within one compact module, and it integrates quickly with existing control systems through proportional 4–20 mA outputs and six programmable alarm relays.
