Dynamic reference diffuse sensors
DRT 25C - The one for everything.
Reliable detection of confectionery and baked goods.
No readjustment when changing objects.
The DRT 25C dynamic reference diffuse sensor – an innovative new product from Leuze – is specially designed for the detection of confectionery and baked goods. Thanks to intelligent CAT technology it reliably recognizes flat and spherical products, transparent to high-gloss films as well as irregular shapes and contours.
The better diffuse sensor
No matter what shape the confectionery and baked goods and their packaging have: With its three light beams, the DRT 25C reliably detects the front edges of the objects and ensures that the process goes smoothly without any machine downtime. Thanks to the wide scan, even products with holes, such as cookie curls, are safely detected as a continuous object. For this, not all three light spots need to be on the object.
From transparent to high-gloss
Packagings with different colors and transparency are safely detected as a ‘deviation’ from the conveyor belt surface due to the reference technology. This means that even machines that process a wide range of films can be equipped with a single sensor type.
No setup time when changing products
When performing the initial setup, the conveyor belt surface is taught in as a point of reference with the teach button. After a product changeover, it is not necessary to adjust this setting, as the point of reference remains the same. In addition, the mounting position and the alignment of the sensor itself can be continuously used for the widest variety of objects. This means that no setup effort is required for the sensor when changing products.
One-of-a-kind CAT technology
The DRT 25C works with the conveyor belt surface as a dynamic reference for the detection of objects. With this method, the surface characteristics of the conveyor belt are taught in via the teach button. The sensor will then detect all objects that do not correspond to the conveyor belt surface. The DRT 25C thereby functions independent of object, making it more stable than classic diffuse reflection sensors. Even contamination on the conveyor belt can be compensated with the Contrast Adaptive Teach technology.
