Extrusion International 1-2019

33 Extrusion International 1/2019 Erhardt+Leimer at ICE Europe 2019 New edge sensor with extra wide measuring range At ICE Europe (12 to 14 March, Mu- nich, Germany), Erhardt+Leimer will present new and proven products from the sector of measuring and au- tomation technology for the convert- ing industry. Measuring range three times larger than before The new digital infrared wide band sensor FR 61 is particularly suitable for the precise acquisition of the position of homogenous, opaque materials. Even transparent mate- rials (transparency of up to 70 %), e.g. cloudy plastic films can be de- tected. The particular advantage of the sensor is its large measuring range: 3 variants with measuring ranges of 160 mm, 320 mm and even 480 mm are available. The web can be ac- quired and guided in the entire sen- sor field of view. Format and width changes during production can be undertaken reproducibly, quickly and cost-effectively because the manual adjustment of the sensors re- quired in the past is no longer neces- sary. It is also possible to evaluate up to 4 edges simultaneously. The actual edge position and diag- nostic information are displayed on the sensor’s integrated display. The Ethernet interface on the device and an integrated web server make pos- sible servicing and access to status values, warnings and alarms as well as the complete configuration using a standard web browser. The wide band sensor operates with the transmitted light principle. Due to the overlapping arrangement of individual infrared light paths, there is a correspondingly large measur- ing range with a high resolution of 0.01 mm and high linearity. An integrated exposure controller largely compensates for effects such as external light and soiling. Option- ally, the sensor is available with an air purge system. Triggered scanning of color lines or other contrast features With the proven FE 52, E+L will also present a color line sensor with a trigger mode such that web guiding based on a single criterion directly in the printed image is possible. This in- dividual criterion can be a color line or a contrast feature, for example an individual letter. As such, technical orientation lines used only for web guiding and cut off after the printing process are no longer required. Along with the sensors, Erhardt+Leimer will present at ICE its systems for web guiding, web ten- sion control and the measurement of the weight per unit area and the thickness of coatings.
