摘要
文章利用热敏电阻和非平衡电桥设计出了可以测量热力学温度、摄氏温度以及华氏温度的电路,并制成温度计。通过对这个温度计的校准表明:利用热敏电阻和非平衡电桥制作的数字温度计电路简明、结构简单、精度较高、达到了设计要求。
The author uses a thermistor and unbalanced bridge design a circuit, which can measure the thermodynamic temperature, Celsius and Fahrenheit temperature, and made a thermometer.Through the calibration of the thermometer shows that： using thermistors and non-balance bridge production of the digital thermometer circuit concise, simple structure, high precision, meet the design requirements.
