Sensors for steelworks

July 2008 Sensors & Transducers

American Sensors produces innovative measuring devices, many laser-based, for the arduous conditions found in steel mills. Many desirable parameter measurements that were previously impractical can now be reliably undertaken. Some of the specific sensors available include:

* Laser scanning systems that can be used for applications like refractory wear monitoring and bulk materials profiling.

* Infrared scanners used for edge detection, slab centring and slab width control.

* Scanning pyrometers for temperature profiling.

* Capacitive and X-ray gauges for thickness measurement down to 5 μ absolute accuracy.

* Laser velocity meters that can measure the speed of hot products travelling at 240 m/s with 0,02% accuracy.

* Multiple wavelength pyrometers that can measure to 3000°C with 5°C accuracy.

* Heavy duty magnetic switches that have a 200 mm detection range for positioning work.

* Microwave devices for liquid level measurement in furnace torpedo cars.

ASC has a range of solutions for use in melting shops, continuous casters and hot or cold mills.
