The ultrasonic measuring system GreCon DELAMINATIONCONTROL detects inhomogeneities in panel-shaped materials, such as wood based panels, inline. Size and location of defective areas are recorded and visualised. Thus, defective panels can be identified and sorted out in time. The measuring method supplies reliable results for both thick panels of up to 55 mm thickness and light panels of a density of < 550 kg/m³. Depending on the quality requirements, different defect types can be configured to enable multi-stage quality sorting. Advantages at a glance Early detection and localisation of hidden errors Recognising performance reserves through process trending High availability and operational reliability of the system Avoidance of delamination through early detection in the DC trend Higher productivity by increasing the production speed High reliability of the measured values, as disruptive environmental influences are eliminated by automatic adjustment and integrated contamination control of the monitoring channels Measuring Method Ceramic ultrasonic transmitters are positioned underneath the disc strand. The ultrasonic signal generated by these transmitters penetrates the material and is picked up and analysed by receivers positioned above the product to be measured. An attenuation of the recorded sound energy is registered as a deviation from the target value and signals a possible weak point. In order to achieve good quality measurement results, the general conditions of the measurement should be as similar as possible for all channels.
