The combiSENSOR KSB6430 is specially designed for one-sided thickness measurement of electrode coatings. The sensor system detects material thicknesses from 5 µm to 3 mm with sub-micrometer accuracy. The combiSENSOR KSB6430 combines two methods: a capacitive sensor for detecting the distance to the film coating and an eddy current sensor that measures the distance to the chrome-coated steel roller, which serves as a reference target. The difference between the two signals is used to precisely calculate the thickness value of the coating, with mechanical influences being automatically compensated for.

The non-contact measurement takes places from one side and directly during the production process. The sensor system is insensitive to dirt and offers high temperature stability. Operation is possible in a temperature range from -10 °C to +180 °C, which also allows operation close to the calender.

Advantages:

• Precise thickness measurement of coatings and films from 5 µm
• Reliable measurement with 0.02 µm resolution
• Robust design, ideal for high ambient temperatures
