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.

Measurement of transverse profile tolerances with a capacitive measuring sensor on the film
Capacitive systems can be used in the company's own rotary scanner for blown film tubes (PROFIL).
Contactless capacitive profile measurement C-CAN for barrier films on blown film lines
Precise and effective IBC control for systems with side gusset insertion, with separate width control.
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.
