Features:
- 990 Vibration Transmitter
- Integrated Proximitor Sensor requires no external unit
- Test Input pin for quick verification of loop signal output, using a function generator as the input
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 990-04-70-03-00 Bently Nevada 990 Vibration Transmitter may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

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.
- OEM Equipment Protection: Primarily for original equipment manufacturers (OEMs) of equipment such as centrifugal air compressors, small pumps, motors, or fans, which require simplified 4-20 mA vibration signals for their control systems.
- Confined Space Monitoring: Compatible with the 3300 NSv proximity probe, optimized for small shafts and confined installation spaces.
- Condition Monitoring: Converts raw probe signals to peak-to-peak vibration amplitude (4-20 mA) for continuous health trend analysis and alarms for critical equipment.
