CENTERWAVE 6000

Advantages of the new millimeter wave technology

Even without any knowledge of the properties of the extruded materials and its temperatures, the CENTERWAVE 6000 seamlessly measures the outer dimensions as well as the wall thicknesses for the complete circumference, providing a precision to a previously unknown degree.

At least one or 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.

Replacement of conventional technologies

For the development of the technology on the basis of a CW-millimeter wave chip, the goal of creating a non-contact measuring device at the extrusion of pipes that is maintenance-free and durable, was decisive. By independently identifying the characteristic values of the material, the CENTERWAVE 6000 generates the measuring values with the highest precision, without the need for specifications regarding the material parameters.

The CENTERWAVE 6000 is going to provide highly precise measuring values at different positions of the production line (even in the hot area) as there are no coupling mediums needed, temperatures are not decisive and no calibrations are necessary.

Product spectrum

The millimeter wave technology is suitable for the measurement of all kinds of plastic pipes with a diameter from 60 to 1,600 mm. The industrial PC ECOCONTROL 6000 offers, besides a numeric presentation of the measuring values, also a graphic visualization as well as extensive trend and statistical data features.

The calculation of virtual measuring values at the position of the extruder allows the line manager to react quickly to changes. Even with larger delay times between the position of extrusion and the measurement an effective and fast control of the wall thickness and especially the elimination of excessively consumed material is guaranteed.
