133442-01 3500/50 Main functions
Receive input signals from proximity probes or magnetic sensors to determine shaft speed, rotor acceleration, or rotor direction.
Compare these measured values with user programmable alarm set points and generate alarms when the set points are violated.
Suitable for dynamic speed monitoring of large and medium-sized rotating machinery such as steam turbines, compressors, fans, water pumps, coal mills, gearboxes, and motors.
