Description

technical field

[0001] The invention relates to the electromechanical field, in particular to a thickness detection device and method. Background technique

[0002] On-line continuous thickness measurement of sheet-like items, such as paper, bills, plastic films, textile items, etc., is playing an increasingly important role in the production, testing, processing, and recycling of their products. In recent years, the detection technology of film thickness through electrostatic induction between electrodes has been continuously researched and explored. For example, the patent of publication number CN210302446Y discloses a capacitive paper thickness sensor, which mainly converts the capacitance change of the capacitor into the oscillation frequency The change of the frequency is converted into a change of voltage by the frequency-voltage conversion module. The patent with the publication number CN103363887A also discloses a detection method of material thickness, which uses t...
