- Abstract
An intelligent metal linear expansion experimental instrument scheme brings for the existed problems aimed at measurement equipment of metal linear expansion coefficient. System by the processing core STC89C52RC adopts Holzer displacement sensor SS495A to measure displacement of metal bar expansion. Temperature sensor DS 18B20 collects the temperature of metal tube by adopting PID algorithm to control temperature as constant and using the collected data of upper computer software to obtain the final coefficient of metal linear expansion. Experimental shows the scheme is steady with high accuracy.
