摘 要: 酒精生产过程中,需要对蒸馏塔多点温度进行检测。采用新型薄膜铂温度传感器设计了多点温度检测系统,使用正反馈型线性校正电路使输出电压与温度成线性关系,从而提高了检测系统的测量准确度。本系统的特点是电路设计新颖、测温准确度高、实用性强。 In the process of producing alcohol, the multipoint temperature in distilling towers needs to be measured. A multipoint temperature measurement system is designed by using a new type film platinum temperature sensor. The linearity correction circuit of positive feedback can make the output voltage be linear with the temperature, so the measurement accuracy of the system is improved. The system has such advantages as novel circuit design, high accuracy and good practicality.
