Leuze introduces DRT 25C dynamic reference diffuse sensor

June 23, 2020 - The primary and secondary packaging of confectionery and baked goods can be challenging: The DRT 25C dynamic reference diffuse sensor from Leuze works to solve this problem with reference technology and three light spots.
 
Leuze's detection expert – the DRT 25C – works to meet the requirements of packaging machines for confectionery and baked goods with reference technology.
 
Sensors must continuously detect a wide range of products and films on the conveyor belts of primary and secondary packaging machines for confectionery and baked goods (HFFS, FS, Thermoform, or VFFS). The packaging machines keep running without interruption, even if the product or packaging material changes.
 
Leuze developed the DRT 25C dynamic reference diffuse sensor with its detection method for this area of application. The sensor works with three light spots and uses reference technology. The latter references the conveyor belt instead of the product and that is what makes this technology so unique. In the first step, the surface characteristics of the belt are taught in. This enables the sensor to subsequently 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 the color, gloss, or transparency do not influence the detection. The DRT 25C uses its three light spots to detect the entire spectrum: small, flat, or also tall and spherical products.
 
The DRT 25C is 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.
