传感器+运算放大器+ADC+处理器是运算放大器的典型应用电路，在这种应用中，一个典型的问题是传感器提供的电流非常低，在这种情况下，如何完成信号放大？对于微弱信号的放大，只用单个放大器难以达到好的效果，必须使用一些较特别的方法和传感器激励手段，而使用同步检测电路结构可以得到非常好的测量效果。这种同步检测电路类似于锁相放大器结构，包括传感器的方波激励，电流转电压放大器，和同步解调三部分。需要注意的是电流转电压放大器需选用输入偏置电流极低的运放。
导体线芯长期工作温度为70℃、95℃两种，电缆敷设温度不低于0℃。电缆的推荐允许弯曲半径如下：无铠装电缆，应不低于电缆外径的6倍；铠装或铜带屏蔽电缆，应不低于电缆外径的12倍；屏蔽软电缆，不低于电缆外径的6倍。
2.485信号线可以使用平行线作为布线，也可以使用非屏蔽线作为布线。由于485信号是利用差模传输的，即由485+与485-的电压差来作为信号传输。如果外部有一个干扰源对其进行干扰，使用双绞线进行485信号传输的时候，由于其双绞，干扰对于485+，485-的干扰效果都是一样的，那电压差依然是不变的，对于485信号的干扰缩到了最小。

PID自整定开始后，只有过程反馈值超出了该区域，PID自整定调节器才会认为它对输出的改变发生了效果。这个值用来减少过程变量的噪声对自整定的干扰，从而更**地计算出过程系统的自然振动频率。如果选用自动计算，则缺省值为2％。如果过程变量反馈干扰信号较强（噪声大）自然变化范围就大，可能需要人为设置一个较大的值。但这个值的改变要与下面的偏差值保持1:4的关系。偏差：偏差值决定了允许过程变量偏离设定值的峰峰值。
