摘要

Exhaust temperature of the marine engine is commonly measured through thermocouple.Measure deviation will occur after using the thermocouple for some time due to nonlinearity of thermocouple itself, high temperature and chemical corrosion of measure point. Frequent replacement of thermocouple will increase the operating cost. This paper designs a new intelligent instrument for solving the above-mentioned problems of the marine engine temperature measurement, which combines the conventional thermocouple temperature measurement technology and SCM(single chip microcomputer).The reading of the thermocouple is simple and precise and the calibration can be made automatically and manually..
