Bently Nevada 3500/50 133388-02 Tachometer Module

Description of 3500/50 Tachometer Module The 3500/50 Tachometer Module is a two-channel module designed to receive input from proximity probes or magnetic pickups (with some exceptions) to measure shaft rotational speed, rotor acceleration, or rotor direction. It compares these measurements against user-configurable alarm setpoints and triggers alarms when thresholds are exceeded.
