Metrological Assessment of an Electronic System for Monitoring the Geometrical Parameters of Cylindrical Profiles

To manage the quality of finished mill products, an electronic system for monitoring the geometrical parameters of cylindrical profiles was developed at the University of Ruse "Angel Kanchev". The aim of the electronic system is every cylindrical profile to be accompanied by a certificate of quality. Experimental researches have been conducted to evaluate the metrological accuracy class of the eight linear optoelectronic converters which are used as sensors. The intrinsic measurement error of the linear optoelectronic converters, define the accuracy class of the developed electronic system.
