Abstract:
Tactile distance measurement systems with uncertainties in the micrometer range cannot be used in hot environments with temperatures above 800°C. A green laser-triangulation system with appropriate optical filters can meet these requirements. A measuring system was build up and tested at room temperature and in two different heat treatment furnaces at temperatures up to 900°C. Good linearity of the system and acceptable correspondence between measurements and published reference values could be observed. The results show the suitability of the system for distortion measurements in heat treatment furnaces.
