One of the products showcased at the ITMA Asia + CITME by the producer of automation and quality assurance systems Erhardt+Leimer GmbH, Stadtbergen/Germany, is the new Elmeta MDA1005 / MDA1006 metal detector with increased accuracy. It reliably detects even very small metal particles across the entire width of the textile material. Signal LEDs on the sensor indicate the position of the metal particle in the web. The integrated segment-wise evaluation as well as the gain setting and a reset button ensure straightforward commissioning. The device detects metal particles at production speeds from 2-500 m/min (depending on the size and material of the particles). The special scanning surface and the aluminum housing prevent damp webs or electromagnetic interference affecting the detection result. The device can be used for dry and damp textiles and for nonwovens. It can be installed in any orientation in any production machine. The only requirement is that there must not be any moving parts, e.g. rollers, installed within an area of 500 mm.
By detecting even very small metal particles, the MDA1005/1006 can prevent costly damage that may occur on the downstream calender rollers and shearing tools. Furthermore, the risk of catalytic reactions in wet finishing is minimized.
Apart from the metal detector, Erhardt+Leimer will exhibit the Elcut cutting systems, the Elsmart web guiding and spreading system, the Elstraigth weft straightening system, the Elfeed tenter guider, Eeltens equipment for web tension measurement and control and the camera-based Elcount pick and course counter.
