The Bently Nevada 990 is a compact two-wire vibration transmitter. It is intended for applications that need a proportional vibration signal sent into a plant control or monitoring system.
What It Does
The 990 accepts input from a compatible 3300 NSv proximity probe system and conditions the measurement into an industrial output signal.
How It Differs from a 3500 Rack
A 3500 rack is a modular machinery protection platform with dedicated monitoring modules, rack communication, power supplies, and configurable system functions. The 990 is a much more focused transmitter device.
What to Verify
Check the complete 990 ordering number, the connected probe system, the system length, measurement range, and the control-system input requirement.
Use the Datasheet
The manufacturer datasheet should be the source for wiring, signal range, mounting, approvals, and environmental limits. A product family summary should not replace those details.
Use the applicable manufacturer datasheet or manual for final configuration, wiring, installation, and engineering limits.
