Bently Nevada Model 990-04-50-03-00 Industrial Vibration Transmitter

Bently Nevada 990-04-50-03-00 Vibration Transmitter Overview

The Bently Nevada 990-04-50-03-00 is a loop-powered vibration transmitter engineered to provide precise 4–20 mA output signals for industrial machinery monitoring. This robust device integrates seamlessly with 3300 NSv proximity probe systems to ensure reliable equipment protection. By converting raw vibration data into a standardized current signal, it allows facility managers to monitor critical assets like pumps and compressors through existing control systems.

Technical Performance and Application Specs

This vibration transmitter serves as a compact, essential component for centrifugal air compressors, small pumps, motors, and industrial fans. It transforms raw proximity probe inputs into a standardized 4–20 mA signal, which facilitates direct integration into existing programmable logic controller (PLC) or distributed control system (DCS) architectures.

By utilizing a two-wire, loop-powered configuration, the transmitter minimizes installation complexity while maintaining high measurement precision in challenging industrial settings. The unit functions by processing signals from 3300 NSv proximity probes and their corresponding extension cables. Users can configure the system for either 5 m or 7 m total system lengths depending on specific site requirements.
