【Abstract】 A new type of alloy linear contraction detector has been developed. In the system, Intel 8031single chip microcomputer and displacement sensor produced by the author are used . It can measure and demonstrate the temperature and linear contraction rate of alloy synchronously. This tester has advantages of small size,high accuracy high stability,strong ability of interference resistance and convenient operation.更多还原
