Product Description

The Bently Nevada 990-05-XX-02-01 Vibration Transmitter is a 2-wire, loop-powered device designed for original equipment manufacturers (OEMs) of centrifugal air compressors, small pumps, motors, or fans. It converts raw vibration data from Bently Nevada’s 3300 NSv proximity probes and matching extension cables (available in 5 m and 7 m system length options) into a proportional 4-20 mA signal for integration into machinery control systems. This transmitter provides reliable vibration monitoring for non-critical machinery, enabling predictive maintenance and enhanced operational safety.
