ることを特徴とする監視装置。 A laser light irradiation device that irradiates laser light onto the surface of a manufactured film sheet that is continuously running, and an O that converts the laser light that has passed through the film sheet surface into an output voltage.
It is equipped with a signal processing device to which the output signals from the E converter and the OE converter are guided, and it is possible to determine the presence or absence and nature of abnormalities by processing data on changes in the amount of transmitted laser light irradiated onto the film sheet surface. Features of monitoring equipment.
