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:

141612 Rev. P

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
