EMG - Strip Measurement Inductive Sensor (SMI) Brochure

The measuring principle of the SMI sensor family (Strip Measurement Inductive) is based on electromagnetic induction. Two centre sensors are arranged at the strip edges at right angles to the strip pass line level and symmetrically to the system centre, and they are configured in such a way that the strip passes between the sensors as centrally as possible. The centre sensor that is located above the strip functions as a transmitter and the opposite sensor functions as a receiver.
