NDIR系统存在的一个主要问题是随着时间的推移，如何准确地知道发送给检测器的光线变化是否真的因气体吸收所引起，而不是光源变化或者舱室污染所引起。尽管在NDIR系统工作之初进行校正是可能的，但是为了应对随着时间推移而出现的光源变化和舱室污染问题，要求不断进行校准。这样做成本很高昂、耗费时间，并且在长期现场运行过程中也不可行。解决这个问题的一个方法是，在你的系统中使用一条基准通道。该基准通道包含一个检测器，在没有光线吸收的范围内测量光源。现在，气体浓度由两个发送光量之比来决定。光源偏差引起的任何误差现在都被抵消。这种偏差导致长期漂移，其出现在较大的时间段内。因此，无需同时对基准和有源通道进行采样。你可以使用一个输入多路复用器(MUX)来在两条通道之间切换，从而降低系统成本和复杂程度，并同时维持度

在NDIR系统中用作红外检测器的热电堆根据其接收的入射光多少(单位为瓦特)来产生电压。被测气体类型、其吸光系数和气体浓度范围都影响热电堆检测器的入射光线量。它产生热电堆输出电压(范围通常为数十μV)。因此，你需要设计出具有使用不同增益放大热电堆输出电压功能的电子支持组件。可以通过一个含内置PGA的模拟前端(AFE)来处理这种情况。要求使用数百到数千V/V范围的增益设置，来把小热电堆信号放大到系统全刻度模数转换器(ADC)，从而实现大系统度。
