七、精密型温度控制电路温度控制的执行驱动部件采用双向可控硅,在回路中串入加热丝元件升温,总的温控原理见原理方框图,下面逐一予以介绍。本仪器的温度控制电路分成二路,一路控制色谱柱系统的加热恒温装置,它由温控电路中的IC_1、IC_2、IC_3、T_1、T_2、T_3、等元件组成,这个电路产生的触发移相脉冲带动外围部件的光电耦 Seven, precision temperature control circuit temperature control the implementation of the drive components using two-way thyristor, the circuit in the string into the heating wire components, the general principle of temperature control principle block diagram, the following one by one to be introduced. The instrument temperature control circuit is divided into two, all the way to control the heating system thermostat column system, which consists of temperature control circuit IC_1, IC_2, IC_3, T_1, T_2, T_3, and other components, the circuit trigger phase shift Pulse driven peripheral components of the optocoupler
