Product Overview
The Bently Nevada 990-05-XX-03-05 is a two-wire seismic velocity transducer designed for measuring absolute vibration in machine casings, bearing housings, and structural components.
This 990 Series vibration transmitter uses a moving-coil mechanism to produce a voltage output directly proportional to vibration velocity. It is widely applied in industrial machinery protection and condition monitoring systems.
Although discontinued by the manufacturer, it remains highly reliable, and Radwell provides a 2-year warranty on this unit.
