Measurements on Hot Metals
The working principle is based on the well known laser triangulation technology, here with robust, fast, reliable measuring sensors, optimized to work on high temperature metals (up to 1000°C, 1300°C, 2200°C). A small laser beam, projected on the target surface and observed by an angled optical system, provides the measure of the material distance from the head in form of analog and digital signal.
Many models are available with measuring ranges up to 2000 mm and working distances up to 5000 mm. Special models upon request.
In order to operate in heavy industrial environments in presence of high temperatures, dust, steam, etc…, the LLS laser heads are built to provide a robust mechanical and thermal protection to the integrated instrumentation. They measure from great distance, without contact and without wear.
Two laser measuring heads are mounted on a heavy-duty I-Frame with a certain inclination angle with respect to the surfaces of the target material. This setup allows to work in more protected position at the side of the material instead of over and under it as in the typical C-Frame configuration. A thin laser line is projected on both material surfaces and it is observed by the relevant camera through an optical system. Each head measures the position of the relevant surface along the laser line. Material thickness is calculated from the combination of the measured points, given the distance and the inclination between the two heads.
The gauge is suitable to measure on the production line materials with high thickness variations, hot, or cold, stationary or moving. The system precision is proportional to the measuring range and independent from material thickness and composition
The gauge is water cooled and equipped with permanent self-calibration system. It works on materials with temperature up to 1300°C and thickness up to 200 mm.
