     粉尘浓度检测仪主要有电容法、β射线法、光散射法、光吸收法、摩擦电法、超声波法、微波法等粉尘浓度在线测量方法。 电容法的测量原理简单，但电容测量值与浓度之间并非一一对应的线性关系，电容的测量值易受相分布及流型变化的影响，导致较大的测量误差；B射线法虽然测量准确，但需要对粉尘进行采样后对比测量，很难实现粉尘浓度的在线监测；超声波法、微波法测量粉尘浓度还处于试验研究阶段，市场上成型产品较少。市场上主要采用光散射法、光吸收法、摩擦电法进行粉尘浓度在线监测，形成的产品较多，并成功地应用于粉尘浓度测量和煤矿井下粉尘浓度测量上。

In April, 2010, California South Coast Air Quality Management District (SCAQMD) passed Rule 1155, requiring all industries that operate baghouses and dust collectors with 7500 ft2 or more of filter area to install particulate monitors for filter leak detection and to have no visible emissions.

Asphalt plant operators were concerned with the new rule. In prior years, many plants tried to be proactive by installing other charge sensing devices, triboelectric broken bag detectors, and opacity monitors. The experiences were all similar. Batch processing with high moisture and sticky particulates caused repeated unreliable measurements and false alarms, significantly hampering production. Frequent maintenance and confusing set up and were also common.
