The Bently Nevada 990 Vibration Transmitter is intended primarily for the original equipment manufacturers (OEMs) of centrifugal air compressors or small pumps, motors, or fans who prefer to provide a simple 4 to 20 mA proportional vibration signal as the input to their machinery control system.
The transmitter is a two-wire, loop-powered device thataccepts input from our 3300 NSv proximity probe and itsmatching extension cable (available in 5 m and 7 m systemlength options).
The transmitter conditions the signal into appropriate peakto-peak vibration amplitude engineering units, and providesthis value as a proportional 4 to 20 mA industry-standardsignal as the input to the control system where machineryprotection alarming and logic occurs.1

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description.
Integrated transmission: Without the need for an external preamplifier, the probe signal can be directly processed into a 4-20 mA output.
Dynamic output: Provides non isolated "PROX OUT" and "COM" terminals and coaxial connectors for viewing raw vibration waveforms and gap voltages through devices such as oscilloscopes.
Strong protection: Adopting sealed packaging, suitable for high humidity environments with up to 100% condensation.
Compatibility: Typically used in conjunction with 3300 NSv proximity probes and matching extension cables.
