A method and device for the evaluation of signals of a sensor, in
particular of a microwave sensor, is proposed for the detection of the
thickness, mass, density and/or moisture of at least one fiber sliver
moving relative to the sensor on drafting equipment. A high-frequency unit
assigned to the sensor produces a number of first digital signals in
digital form of the current state of the (at least one) fiber sliver. The
method according to the invention is characterized in that a second
digital signal, representing the current sliver thickness or sliver mass
of the (at least one) fiber sliver and which is then used to control the
drafting equipment and/or to judge the fiber sliver quality, is formed
according to an algorithm from the first digital signals made available.
In addition a suitable device for the evaluation of the signals of a
sensor is proposed.
