POSITION MEASUREMENT

We are proud, for example, of our patented and radar-based strip position measurements. They measure the strip position in continuous furnaces without contact, at a great distance and without great installation effort. It does not matter whether the strip is guided vertically or horizontally.

All our different sensors are usually coupled to our strip guiding systems. However, they also operate independently as stand-alone measuring systems. Integration to external strip guiding systems is possible at any time. Numerous interfaces are available for this purpose.

After all, the heart of a stable control system is a robust, reliable and long-term stable measurement.

Depending on

  • the measuring task,
  • 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 and installation location together with you.

Optical camera systems, systems with photodiodes, inductive and capacitive sensors are available for determining the strip edge position or strip center position.

Our sensors for position measurement at a glance

Our latest development, the NIGduo optical camera system, also works with illumination units installed above the strip. This avoids disturbing slits/openings in the guide tables below the strip. Thus, contamination caused by dripping liquids, dust and scrap pieces is avoided as far as possible. On the other hand, accessibility to the measuring system components is much easier. Any maintenance and cleaning work that may be required can therefore be carried out more quickly and without major dismantling effort. A solution that is both compact and smart.

With the laser-based strip position measuring system NIGlas , we place both the camera and the laser in a common housing above the strip. This simplifies the installation. The pre-calibrated measuring head only needs to be mounted at a defined distance. NIGlas has the further advantage of being able to measure strip contours in addition to those already mentioned for NIGduo. This additional feature is used to compensate for the width information.

NIGRAD – RADAR SYSTEM FOR USE IN CONTINUOUS FURNACES

During the development of our patented radar measurement technology, strict attention was paid to ensuring that time-consuming and cost-intensive maintenance work on the measurement technology or cooling systems does not occur in the first place.

NIGDUO – STEREOSCOPIC CAMERA SYSTEM WITH BACKLIGHT OR INCIDENT LIGHT

The use of the stereoscopic measuring principle has been state of the art for a very long time. We also rely on this technology for our NIGduo width and position measuring system. High accuracies are achieved with this method. Learn more about the 4-3-2-1-0 method.

NIGLAS – CAMERA SYSTEM WITH LASER

The NIGlas measuring system, which operates according to the triangulation principle, is our most compact width measuring system. 

AWL – SYSTEM WITH PHOTODIODE SENSOR TECHNOLOGY AND LED TECHNOLOGY

Neither extraneous light nor horizontal or vertical pass line fluctuations affect this measurement!

AWC – CAPACITIVE SENSORS

Wear parts as well as moving parts are nowhere to be found in this system. Consequently, maintenance work is reduced to a minimum.

NS-CPC – INDUCTIVE SENSORS, ESPECIALLY FOR PICKLING LINES

Our NS electromagnetic induction guide system is predestined to be used where others despair due to dirt, vapours, oil mist and corrosive gases.
