One-sided thickness measurement of plastics Product Technology

The combiSENSOR series sets new standards in non-contact thickness measurement. These precise sensors combine the advantages of eddy current and capacitive sensor technology in a single housing. This innovative technology enables the micrometer-precise measurement of material thicknesses, e.g. of battery coatings and plastic films. Target thicknesses as low as 5 µm can be detected. In addition, their robust design ensures that the sensors work reliably even in harsh industrial environments with high temperatures.

The combiSENSOR series is the optimal solution for inline thickness measurements of electrode coatings, coated metals and films requiring highest precision and reliability.

Sensor system for precise thickness measurement of electrode coatings, combiSENSOR KSB6430

One-sided thickness measurement of electrode coating
Target thickness: 5 µm to max. 3 mm
Measurement on steel rollers with chrome coating
Temperature range of sensor -10 °C … +180 °C
High resolution 0.05 µm

The combiSENSOR KSB6430 measures the thickness of electrode coatings from a material thickness of just 5 µm. The thickness is measured on a chrome-coated roller which guides the material. Due to its robust design and high accuracy, the KSB6430 is ideal for inline thickness monitoring in battery film coating processes.

Sensor system for precise thickness measurement of plastic films and coatings, combiSENSOR KSS64x0

One-sided thickness measurement of plastic film & coated metals
Target thickness: 40 µm to max. 6 mm
Measurement on metal rollers or metal plates
Temperature range of sensor -10 °C … +85 °C
High resolution 0.05 µm

The combiSENSOR KSS64x0 enables precise, non-contact thickness measurement of non-conductive materials such as plastic films or coatings on metallic reference objects. The sensor's robust design makes it ideal for use in a wide range of industrial applications.

Measuring principle

The combiSENSOR measures the coating thickness with a capacitive sensor to measure the distance from the coating and an eddy current sensor to measure the distance from the metal roller. The difference between the two signals provides the total thickness of the coated film, while mechanical influences are automatically compensated for.
