2NTC热敏电阻线性化的电路设计通常利用单片机对NTC热敏电阻进行线性化,不仅电路复杂,而且要做大量的计算,下面介绍一种利用四通道智能温度传感器MAX6691实现NTC热敏电阻线性化的电路,如图2所示。 例如在污水行业经常遇到,判别方法:可采用前述气泡判别的方法,此时以指针式万用表测量电极电阻,可发现电极的回路电阻明显变高,若以水对比,国产MF30万用表以×1K的量程测量,所测得得阻值不会大于100k。FINE MECHATRONICS/FINE TRON,FCC2-30TF,FCC2-100TF,FCC2-200TF FCM1-50KG,FCM1-100KG,FCM1-200KG,质量好

所以范围度仍然得不到拓宽,值得庆幸的是,自从仪表实现智能化以后,人们了有力的工具,因为仪表的计算功能大大增强,可以根据式(1)在线计算流出系数,从而修正雷诺数对流出系数的影响,将节流装置,差压变送器,压力变送器。 所有的输入量,包括主电压,主电流,进油流量,回油流量都转换成为脉冲信,仪器采用AT89C52中的两个内部计数据器和8253的两个计数器,在定时中断的控制下定时对以上信计数,即可测出以上数据,实时时钟由DALLAS的DS12887电路提供。FINE MECHATRONICS/FINE TRON,FCC2-30TF,FCC2-100TF,FCC2-200TF FCM1-50KG,FCM1-100KG,FCM1-200KG,质量好
