Capacitive Gauging System for Blown Film Lines

NON-CONTACT SKYMEX is a capacitive profile gauge for blown film extrusion lines. It guarantees a continuous and precise measurement of the film profile and is installed on a patented triple movement telescopic.

The dielectric characteristics of the measured film produce a signal variation proportional to the film thickness. The capacitive sensor is mounted in the centre of the beam, the oscillatory rotation system allows for the rotation of the sensor around the bubble, reading the angular position and allowing the generation of a circumferential profile of the thickness over 360°.
