【Abstract】 The temperature sensor of automobile engine for taking measure of cooling liquid was systematically studied,Its structure and work principle were analyzed. The regularity of the technology to fabricate NTC thermistor in use for temperature-sensing components was researched. The assembly of NTCR temperature sensors and their influence on component were analyzed and inverstigated. In orderto enhance the stability and the measure accuracy of these components a effective method to reduce the temperature rise produced by thermistor itself was presented-更多还原
