Non-contact measuring sensor
PLAST-CONTROL has been manufacturing its own capacitive measuring sensor technology for online thickness measurement of films for many years. Especially for sticky and surface sensitive foils the patented measuring head AIR-CC is intended. The AIR-CC is equipped with two parallel arranged sensors, which build up a strongly different capacitive field. This arrangement allows the existing air gap to be measured in addition to the film thickness. Even a permanently changing air gap (range from 100 to 350 μm) does not influence the measurement.
