Featuring a one-of-a-kind reference technology and three light spots, the DRT 25C dynamic reference diffuse sensor meets the high requirements of packaging machines for confectionery and baked goods.
The reference technology references the conveyor belt instead of the product to enable the sensor to detect all objects that do not correspond to the belt surface as "deviations", even if the conveyor belt is dirty or vibrating. With this approach, the surface properties of the products, such as color, gloss, or transparency do not influence the detection. The DRT 25C uses its three light spots to reliably detect the entire spectrum: small and flat or tall and spherical products. Even irregular shapes and contours or products with openings, e.g. cookie curls, are detected. Thanks to the wide scanning range, these are also detected as a continuous piece. Three light spots ensure maximum reliability. The DRT 25C reliably detects the front edges of the objects, ensuring smooth processes and no machine downtime. The wide scanning range detects all types of products, even those with difficult geometries.
The reliable detection of objects—even those with challenging shapes and surfaces—guarantees a high machine throughput and prevents system standstills. Even under difficult conditions such as vibrations or contamination on the conveyor belt. No realignment of the sensor is needed when products or packaging materials are changed over. This significantly reduces the setup time required and enables higher product volumes. The DRT 25C is quickly and easily set up thanks to automatic teaching by means of the teach button. With a universal mounting position for all objects. Additional functions can be conveniently integrated into the machine control via IO-Link. For example a warning message for excessive debris, use of the counter built into the sensor, or locking the teach button.
