PLAST-CONTROL has been manufacturing its own capacitive measuring sensor technology for online thickness measurement of films for many years. Besides the capacitive measuring sensor C-KOPF, sensor C-SCAN offers solutions for barrier and cast films.
The AIR-CC offers another possibility for non-contact measurement.
The type of line as well as the extruded film types determine the type of profile measurement.
PLAST-CONTROL uses exclusively relative working, capacitive methods. The standard is a contacting C-head, which is mounted on a radial adjustment and rotating ring and oscillates around the film bubble. Optionally, a non-contacting measuring head (Air-CC, patented) can also be used. This measuring head is especially suitable for sticky films and films with sensitive surfaces.
Another variant is the C-Scan, also a capacitive measuring system, but also suitable for barrier films.
