We are particularly proud of our patented, radar-based strip position measurements. They measure the strip position in continuous furnaces at a great distance and without great installation effort, without contact and regardless of whether the strip is guided vertically or horizontally.
The sensors are coupled to our strip guiding systems, but they can also operate independently. Numerous interfaces are available to connect them to external strip guiding systems.
Depending on your requirements for accuracy, the strip run and the space conditions in the production line as well as the often adverse ambient conditions, we select the right sensor type together with you. Optical camera systems, systems with photodiodes, inductive and capacitive sensors are available.
Our sensors for position measurement at a glance:
In our latest developments, the NIGDuo optical camera systems, the illumination units can be installed above the belt, thus avoiding disturbing slots/openings in the guide tables below the belt and eliminating the contamination caused by dripping liquids, dust and scrap pieces. Accessibility is much easier, so that maintenance and cleaning work can be carried out more quickly and without major dismantling effort. Due to the stereoscopic measuring principle, the measuring accuracy is only slightly affected by vertical strip movements.
The laser-based tape position measuring system NIGLas has both the camera and the laser in a housing above the tape. This makes installation very simple; the pre-calibrated measuring head only has to be attached at the previously defined distance. In addition to the advantages mentioned for NIGDuo, NIGLas is also able to consider and compensate for strip contours.
