The capaNCDT TFG6220 measures the thickness of battery film with high precision and is used for quality testing in the form of offline random samples. The TFG6220 is pre-assembled ready for rapid deployment. The thickness is measured by two opposing capacitive sensors whose signals are offset against each other. A measuring insert serves as a flat reference and support surface over which the measuring object is clamped.

A vacuum device sucks in the film and thus ensures wrinkle-free support without damaging the object to be measured. In this way, the thickness measurement is highly reproducible. The TFG6220 consists of a measuring bracket including sensors and an external controller unit. The intuitive web interface can be used to make settings, perform measurements and display and output the measured data.

Advantages:

• Fast offline testing of the film thickness
• High repeatability: 1 µm
• Possible film thickness: < 1 mm
• High-precision results due to automatic smoothing of the film via vacuum
