Collection: Bently Nevada 990/991

Bently Nevada 990/991 is a compact transmitter family for machinery vibration and position monitoring using proximity transducer inputs. The architecture combines a proximity probe system with transmitter electronics that condition the sensor signal and provide a standard process output for connection to control or monitoring equipment. The 990 family is commonly applied to vibration measurement, while 991 configurations are used for thrust or axial position applications depending on model. These transmitters convert shaft movement into continuous monitoring signals that can be used for trending, alarms and integration with PLC, DCS or machinery protection systems. This collection groups components from the same technical family for engineering reference, maintenance planning, system expansion, and replacement of installed equipment. Models are organized by system role so users can distinguish controllers, I/O, communication, power, interface, sensing, and termination hardware without mixing unrelated automation platforms.
