Expert System Solutions has recently developed new no-contact and high temperature measurement techniques for the laboratory and for testing processes. The first results in this field were the automatic heating microscope, essential for studying the fusion process of the frits, glazes and ceramic or metallurgical powders. The double beam optical dilatometer was developed for studying the sintering process, and is capable of carrying out absolute no-contact measurements on a sample subjected to a sintering heat treatment. The latest developments in this technology have produced the horizontal optical dilatometer and the optical fleximeter, two highly innovative instruments which complete the options for analysis of the behaviour of ceramic materials subjected to heat treatments. The four instruments provide a complete view of thermo-mechanical phenomena which occur during the heating and cooling cycles, providing an unequalled depth of analysis and synthesis, and enabling the operator to tackle and resolve even the trickiest problems.
