The operating rate monitoring solution
Speed control relays can receive pulses from all types of sensors such as: Inductive sensors on gear wheels Photoelectric sensors on conveyors Microswitches on cams.
Dependent on rotation or movement speed, the pulse rate supplied to the relay varies. By monitoring the pulse rate, the relays control over or underspeed. The applications include monitoring of rotation speed, transporter or conveyor belt speed, and pump rotation.
