Description
The 990 Vibration Transmitter is intended primarily for theoriginal equipment manufacturers (OEMs) of centrifugal aircompressors or small pumps, motors, or fans who prefer toprovide a simple 4 to 20 mA proportional vibration signal asthe 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†.
