Bently Nevada FBMSVH Filter Module

The Bently Nevada FBMSVH is a high‑performance signal filter module designed for 3500 series machinery monitoring systems. It filters high‑frequency noise and interference from proximity probe and velocity sensor signals, delivering clean conditioned signals to monitor modules for accurate vibration and position measurement on rotating machinery.

This rack‑mount filter unit fits inside the 3500 chassis, providing signal conditioning for multiple sensor channels. It is an essential aftermarket spare for maintenance, overhaul and retrofitting of turbine, compressor and large rotating‑equipment monitoring systems in power plants and petrochemical sites.
