摘要
本文详细叙述了利用正反馈原理,对采用铂电阻测温时出现的非线性函数进行线性化,使显示温度更接近实测温度,并有效地用微机对生产数据进行控制和管理。
This paper recounts the method that converts nonlinear function appeared when measuring temperature by platinum resistor into linear function by positive feedback principle so that the display temperature approaches the measuring temperature com- pletely and the production data can be controled and managed effectinely by microcom- puter.
