Abstract (en)
[origin: CA2669372A1] The invention relates to a device for measuring layer thicknesses, especi ally of a part (18) during or following a coating process. Said device compr ises at least one first and a second distance measuring apparatus (12, 14). The first distance measuring apparatus (12) makes it possible to measure a f irst distance (a) to a surface (20) of a layer (22) that is to be applied to the part (18) while the second distance measuring apparatus (14) makes it p ossible to measure a second distance (b) to an uncoated surface (24) of the part (18), the measurements being taken continuously or at predefined points in time. According to the invention, the device (10) further comprises at l east one third distance measuring apparatus (16) for measuring and monitorin g the position of the first distance measuring apparatus (12) relative to th e part (18), said third distance measuring apparatus (16) making it possible to measure a third distance (c) in a continuous manner or at predefined poi nts in time in order to determine the position of the part (18). The inventi on also relates to a method for measuring layer thicknesses, particularly of a part (18) during or following a coating process.
