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 990-05-50-01-00 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.
This transmitter is primarily targeted at original equipment manufacturers (OEMs) and plant operators, designed to provide them with a simple, cost-effective way to integrate continuous vibration monitoring into their control architecture.
Rotating Machinery Protection: Commonly used in centrifugal air compressors, small pumps, motors, and fans.
Automation System Integration: Provides a proportional signal, easily connectable to PLC, DCS, or SCADA systems for trend analysis and protective alarms.
Predictive Maintenance: Capable of monitoring radial vibration levels, enabling early detection of signs of shaft imbalance or bearing wear, suitable for industries such as petrochemicals, energy, and general manufacturing.
