990-05-XX-01-00 Mod 165335-01 990 Vibration Transmitter

Description
The 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 that
accepts input from our 3300 NSv proximity probe and its
matching extension cable (available in 5 m and 7 m system
length options).
The transmitter conditions the signal into appropriate peakto-peak vibration amplitude engineering units, and provides
this value as a proportional 4 to 20 mA industry-standard
signal as the input to the control system where machinery
protection alarming and logic occurs†.
The 990 transmitter provides the following notable features:
l Integrated Proximitor Sensor requires no external unit
l Non-isolated “PROX OUT" and "COM" terminals plus a
coaxial connector to provide a dynamic vibration and
gap voltage signal output for diagnostics‡.
l Non-interacting zero and span potentiometers under
the Transmitter label supports loop adjustment.
l Test Input pin for quick verification of loop signal
output, using a function generator as the input.
l A Not OK/Signal Defeat circuit prevents high outputs or
false alarms due to a faulty proximity probe or loose
connection.
l Choice of DIN-rail clips or bulkhead mounting screws as
standard options simplifies mounting.
