薄膜铂温度传感器多点温度检测系统

Multipoint temperature measurement system based on a film platinum temperature sensor

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.
