Bently Nevada 990-04-XX-01-00 Vibration Sensor

Engineering Purpose

The 990-04-XX-01-00 is a loop-powered transmitter that integrates the functions of a Proximitor and a monitor. It converts signals from a 3300 NSv probe into a 4-20 mA output proportional to vibration, designed for direct PLC/DCS connection on small-shaft machinery.
