Double sheet sensors is for detecting two or more sheets or sheets that (partially) overlap. This is used in applications such as paper printing machines, folding machines, in the production of silicon wafers and the processing of labels.

The ultrasonic transmitter transmits sound from the bottom to the product layer. The emitted signal makes the layer vibrate. As a result, a small sound wave is spread to the other side of the layer, which is analyzed by the ultrasonic receiver on the other side. In the case of superimposed layers (double layers), the signal is weakened so much that it barely reaches the receiver. Read more about the operation of double sheet detection sensors.
