Description
Bently Nevada 3500/50-01-00-CN 2-Channel Tachometer Monitoring Module
Bently Nevada 3500/50-01-00-CN is a dedicated dual-channel tachometer monitoring module designed exclusively for the Bently Nevada 3500 series machinery protection rack system. This Bently Nevada 3500/50-01-00-CN module receives pulse signals from proximity probes and magnetic pickups to calculate real-time shaft rotational speed, rotor acceleration and rotation direction, and delivers conditioned keyphasor timing signals to other monitoring cards inside the rack for vibration orbit and rotor dynamic analysis. It is widely deployed for overspeed safety protection of all types of critical rotating machinery in heavy process industrial plants.
