The Bently Nevada 990-04-50-01-01 Vibration Transmitter is part of the Bently Nevada 990 Series, which includes a range of vibration transmitters designed for continuous monitoring of vibration in industrial rotating machinery. 

The Bently Nevada 990-04-50-01-01 Vibration Transmitter is designed to monitor the vibration levels of rotating machinery and convert the vibration data into an electrical signal (typically 4-20 mA), which can be sent to a monitoring system, such as the Bently Nevada 3500 Series or other compatible systems. 

 990-04-50-01-01 Provides continuous vibration monitoring for rotating equipment like turbines, motors, pumps, and compressors.

The 990-04-50-01-01  transmitter receives analog signals from the vibration sensors and converts them into a 4-20 mA current loop signal, which can be used by condition monitoring systems.

The 990-04-50-01-01 model supports different types of vibration sensors, including proximity probes and accelerometers, providing flexibility for various applications.
