Abstract
A sensor (,) is proposed for noncontacting thickness gauging on films (,), in particular blown films, with a sensor head (,) and a mount (,) for the sensor head (,), which provides reliable measuring results despite transportation-caused movements of the film (,), and which is particularly suitable for a continuous quality control during the production process. In accordance with the invention, the sensor head (,) comprises at least one noncontacting sensor element for gauging the thickness in accordance with the physical properties of the film (,). Furthermore, the position of the sensor head (,) is adjustable such that the sensor head (,) is held during the entire measuring process at a predeterminable, at least largely constant distance from the film (,).
