Precise online thickness measurement of plastic sheets

Innovative millimeter wave technology offers a precise thickness measurement with no need for any coupling media and independent from material and temperature of the plastic sheet. A calibration is not needed.

The PLANOWAVE 6000 is directly integrated into the production line or it is used for final inspection. The measurement of the sheet is accomplished by using millimeter waves according to the FMCW* runtime method. A linear movable transceiver continuously sends and receives frequency modulated millimeter waves. From the runtime difference the thickness of the sheet is precisely determined.

The visualization of measuring values is processed in real time. The processor system ECOCONTROL offers a numeric display of the measuring values, a graphic visualization and extensive trend and statistical data.

The PLANOWAVE 6000 contributes to repeatable processes, highest quality and productivity at the sheet extrusion.
