Product Overview
The Bently Nevada 3500/44M Velocity Monitor is a four-channel vibration monitoring module designed for use in the Bently Nevada 3500 Series Machinery Protection System.
It continuously measures casing vibration velocity or absolute shaft vibration from seismic transducers such as Velomitor or accelerometer sensors.
The 3500/44M provides precise, real-time monitoring of rotating equipment including turbines, compressors, motors, and pumps.
It converts vibration signals into engineering units, applies programmable Alert and Danger alarm thresholds, and outputs both protection and condition monitoring data to the 3500 rack’s communications interface.
