A design method of a intelligent in-circuit thickness measuring system has been proposed, using Microchip＇s PIC16F877A micro-controller and other necessarily peripheral circuits, such as sensor signal conditioning, LED display, alarm circuit. Linearization process technology has been introduced to minimize the non-liner error of measuring system by program correcting. This thickness measuring system has obviously characteristics of simply circuit, steady performance , low price and high accuracy. This measuring system with good application prospect can be widely used in highly precision industrial measuring.
