Temperature measurement plays an important role in the experiment of missile launch. The circuit is designed to obtain the gas temperature on the bottom of trail cover in the experiment of missile launch. Core of the circuit are amplifier instrument AD623 and two order active low - pass filter circuit, and it uses thermocou ple as temperature sensing element. It has been tested and verified that the circuit can fully record of the gas temperature on the bottom of trail cover in the experiment of missile launch.%在导弹发射试验中,温度测量占有重要地位.为了获得导弹发射试验中尾罩底部燃气温度,设计了一种温度信号调理电路.该电路以仪表放大器AD623、二阶有源低通滤波电路为核心,利用热电偶作为敏感元进行测量.经过验证该电路可以完整记录导弹发射试验中相关温度的数据.
