数字温度测控电路

针对目前较为广泛的温度测试方法中所出现的范围小,操作不方便等问题,作者采用高精度温度传感器,运用高精度运放组成放大电路,有效抑制各种干扰,实现遥测和温度预置功能,并辅以比较控制电路实现恒温.

Temperature Measure and Control by Digital Level

As small scope and inconvinient operation are shortcomings,in the widespread use of temperature testing method,the author of this article adopted high precision temperature sensor,and used high precise amplified circuit to effectively restrain any disturbing,to achieve remoting measure function;achieve temperature prefabricating function,and added comparative control circuit to achieve constant temperature function.This circuit posses the advantages of simple circuit,low power consume,easy operation,direct temperature measurement.
