In ultrasonic measurement, signals of the ultrasonic frequency range are generated, transmitted, received (echoes) and then processed and evaluated. Based on the transit time measurement of the reflecting ultrasonic echoes at the outer and inner pipe wall as well as at the potentially existing boundary surfaces (in case of multilayer pipes), the individual layer thicknesses can be calculated. This requires the coupling medium of water, as well as precise, digitized ultrasonic evaluation electronics. The AUREX ultrasonic systems combine a high accuracy and simple operation for wall thickness and diameter measurement. This means that single-layer and coextruded pipes and tubes can be reliably measured down to a layer thickness of at least 0.05 mm. The interaction of measurement and control ensures overall stabilization of the production process and an efficient production. The early detection of thin and thick sections and the corresponding adjustment at the die leads to a further reduction of production costs. The AUREX systems are available for geometry measurement from 0.5 - 3,000 mm diameter and for 100% wall thickness measurement and flaw detection up to 630 mm diameter.
Advantages:
Detailed product information (wall thickness, diameter, eccentricity, ovality)
Continuous verification of compliance with product specifications
Process automation through control of wall thickness, diameter, weight per meter and mass throughput
Consistent production due to constant wall thickness and centering of tubes and hoses
Material savings of up to 5%
