How It Works

The transmitter measures vibration via a non-contacting 3300 NSv proximity probe and converts the high-frequency vibration signal into an analog 4–20 mA output used by plant control systems for trend analysis, protective alarms, predictive maintenance and automated control logic. 

This type of 2-wire design simplifies wiring (power + signal on same pair) and provides a reliable, linear, proportional vibration output compatible with PLCs, DCS and SCADA. 

Industrial Applications

The Bently Nevada 990-05-50-01-00 vibration transmitter is widely used in:

• Machinery protection systems for rotating equipment

• Industrial vibration trend monitoring

• PLC/DCS/SCADA integration for condition monitoring

• Energy, petrochemical, manufacturing and process industries

• Electric motors, pumps, compressors, fans and turbine systems 

These applications benefit from accurate, real-time vibration signals that help prevent failures, reduce unplanned downtime, and optimize maintenance strategies.
