一、原理和方法 对热电偶测温系统进行动态补偿,常用补偿器。系统的原理框图如图1所示。设已知热电偶的频率特性为H(f),选择的补偿器其频率特性G(f)应近似等于K/H(f)。这时系统总的特性近似等于K,从而得到补偿。这种补偿也可以看作是将热电偶的输出u First, the principle and method Thermocouple temperature measurement system for dynamic compensation, commonly used compensator. System block diagram shown in Figure 1. Assuming that the frequency characteristic of a known thermocouple is H (f), the frequency characteristic G (f) of the compensator selected should be approximately equal to K / H (f). At this point, the total system property is approximately equal to K, which is compensated. This compensation can also be seen as the thermocouple output u
