KNC-601 Linear Scanner 3G - Non-contact thickness gauge for MDO and cast film lines

KNC-601 Linear Scanner 3G

The KNC-601 Linear Scanner is a capacitive, largely contactless thickness sensor for measuring the profile of flat films. A unique feature of the KNC-601 is its temperature-controlled air cushion and active film tracking via a linear motor. For inline stretching systems (MDO) for blown film extrusion, we recommend using one KNC-601 Linear Scanner per film half.

Application
  • Largely contactless thickness measurement for MDO and cast film lines
  • For tacky films (e.g., containing EVA or metallocenes) with sensitive outer layers
Special Features
  • Temperature controlled air gap between sensor and film (Unique feature)
  • Adaptive sensor positioning by linear motor (Unique feature)
Technology
  • Capacitive thickness measurement
  • Automatic edge detection by optical sensors
