Bently Nevada 330100-90-00 Vibration Monitoring

Engineering Purpose

The 330100-90-00 is a non-contacting signal conditioner designed to monitor shaft vibration and axial position. It converts the impedance changes from a proximity probe into a linear voltage signal. This specific unit is calibrated for a 9.0-meter system, providing critical data for the protection of turbines, compressors, and other fluid-film bearing machinery.
