Zusammenfassung:The utility model relates to a temperature measuring device for a built-in thermistor of a high-precision vibrating wire instrument, which measures the resistance value of the built-in thermistor of the vibrating wire instrument during frequency measurement through a differential measurement method, and obtains a converted temperature value by combining the resistance-temperature characteristics of the built-in thermistor. Measurement of temperature data of the built-in thermistor of the vibrating wire type instrument is realized. The measuring device provided by the utility model greatly improves the accuracy of temperature measurement data of the built-in thermistor of the vibrating wire instrument. 本申请涉及一种高精度振弦式仪器内置热敏电阻的温度测量装置,该装置通过差分测量法测量振弦式仪器在频率测量时的内置热敏电阻的电阻值,再结合内置热敏电阻的电阻温度特性,得到转换后的温度值,实现振弦式仪器内置热敏电阻温度数据的测量。本实用新型的测量装置大大提高了振弦式仪器内置热敏电阻温度测量数据的准确性。
