TEMPERATURE DETECTOR AND MEASUREMENT METHOD OF THE SAME

摘要

PURPOSE: A temperature measuring device and a temperature measuring method using the same are provided to improve accuracy of the temperature measuring device using two matched constant current sources. CONSTITUTION: A temperature measuring device comprises a temperature measuring sensor(110), constant current sources(131,132), and a converter(140). The temperature measuring sensor is connected to an object and outputs an analog voltage value. The constant current sources are input to both ends of the temperature measuring sensor. The converter is connected to an output end of the temperature measuring sensor and converts the analog voltage signal into a digital output signal.
