The automotive industry and also many other industrial sectors set high demands on multi-layer products. As a consequence, the production process is complex. This applies e.g. to brake hoses but also to floor heating pipes. Frequently, extremely thin barrier and functional layers are demanded which give pipes and tubes their specific mechanical and chemical properties. Conventional ultrasonic measuring techniques have measuring limits at approx. 0.2 millimetres. Inoex offers a new technology where the bottom measuring limit is 0.05 millimetres.
Barrier layers prevent e.g. oxygen from penetrating into the pipe or volatile compo-nents from leaving it. These layers provide products with special mechanical and chemical properties. In order to reduce cost, the target is to make these layers as thin as possible but as thick as necessary. This can only be done when wall thickness is controlled during production. A must in order to guarantee functions at reasonable cost.
Based on many years of experience and innovative ideas, Inoex has further devel-oped proven ultrasonic measuring principles. As a result, function and barrier layers that could not be measured in the past, can now be precisely controlled through intel-ligent ultrasonic sensor technology combined with new algorithms and digital measur-ing techniques. Even data of extremely thin-walled pipes can be precisely recorded which means that high safety regulations can be adhered to and quality demands can be fulfilled. Up to now, ultrasonic measurement was based on the determination of ultrasonic transit times inside a product. Through digitalisation the complete signal is now recorded. This improves signal evaluation and further processing. The complete recording of the signal makes results highly precise and therefore supplies full infor-mation on the product.
