Advantages of the new millimeter waves technology
Even without any knowledge of the properties of the extruded materials and its temperatures, the CENTERWAVE 6000 measures the outer dimensions as well as the wall thicknesses simultaneously at several places of the circumference, providing a precision to a previously unknown degree. Layer thicknesses of multi-layer pipes can also be measured precisely.
Several sensors, so-called transceivers, arranged around the circumference of a pipe, continuously send and receive frequency modulated millimeter waves. Boundary layers reflect these waves, which are detected and demodulated by the receiving unit of the regarding transceiver. These receive signals contain information regarding the distance between boundary layers of different materials. After an algorithmic processing of the receive signals of each sensor, the requested measuring values regarding diameter, ovality and wall thickness are ready for visualization and control within only a few milliseconds.
