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 990-05-50-03-05 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).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
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.
1. Centrifugal Air Compressors & ASU: This is the core application industry for the 990 transmitter.
2. Oil & Gas / Petrochemical: In this industry, it is often used as auxiliary monitoring for large units (such as large turbines) or as independent monitoring for small and medium-sized secondary equipment.
3. Power Generation: In power plants, it is used for the safety and security of auxiliary systems and small and medium-sized auxiliary equipment.
4. Metallurgy & Steel Mills: Applications include large blast furnace blowers, dust collector fans, and rolling mill transmission gearboxes.
5. Water & Wastewater Treatment: Applications include large sewage pumps, aerators, and deep well pumps.
