Bently Nevada 990 Vibration Transmitter 990-05-50-01-00
The 990 Vibration Transmitter is designed primarily for original equipment manufacturers (OEMs) of centrifugal air compressors or small pumps, motors, or fans who require a simple 4 to 20 mA proportional vibration signal as input to their machinery control system.
This two-wire, loop-powered device 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 peak-to-peak vibration amplitude engineering units, providing this value as a proportional 4 to 20 mA industry-standard signal for control system input.
- Integrated Proximitor Sensor requires no external unit
- Non-isolated "PROX OUT" and "COM" terminals plus coaxial connector for dynamic vibration and gap voltage signal output
- Non-interacting zero and span potentiometers under the Transmitter label for loop adjustment
- Test Input pin for quick verification of loop signal output
- Not OK/Signal Defeat circuit prevents high outputs or false alarms from faulty probes
- Choice of DIN-rail clips or bulkhead mounting screws
- Potted construction for high humidity (up to 100% condensing) environments
- Compatible with 3300 NSv proximity probe for installation in tight spaces
