Product Description
Bently Nevada 990 Vibration Transmitter 990-05-50-01-00
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 systemlength options).
The transmitter conditions the signal into appropriate peak to-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:
Integrated Proximitor Sensor requires no external unit
Non-isolated "PROX OUT" and "COM" terminals plus a coaxial connector to provide a dynamic vibration and gap voltage signal output for diagnostics‡.
lNon-interacting zero and span potentiometers under the Transmitter label supports loop adjustment.
Test Input pin for quick verification of loop signal output, using a function generator as the input.
A Not OK/Signal Defeat circuit prevents high outputs or false alarms due to a faulty proximity probe or loose connectio
Choice of DIN-rail clips or bulkhead mounting screws as standard options simplifies mounting.
Potted construction for high humidity (up to 100% condensing) environments. Compatibility with 3300 NSv proximity
probe allows transducer installation in small areas with minimal clearance, typical of centrifugal air compressors.
