在工业温度测控场合K型热电偶因其线性度

好,价格便宜,测量范围宽而得到广泛的使用.但它往往需要冷端补偿,且电路较复杂,调试麻烦,而­ K型热电偶串行模数转换器MAX6675 不但可将模拟信号转换成温度值对应的数

字量，而且自带冷端补偿， 其温度分辨能力达0.25。可以满足绝大多数工业应用场合。-in industrial measurement and control of temperature thermocouple type K occasions because of linearity, and low prices, wide measuring range and have been widely used. However, it often requires a cold junction compensation, and more complex circuits, debugging troubles, and
