金属粉尘浓度检测技术研究

抛光打磨作业场所浮游的可燃性金属粉尘具有爆炸性,实现对其浓度检测具有十分重要的意义。在分析了粉尘浓度2种主要的检测方法即光散射法和电荷感应法检测原理的基础上,设计了相应的粉尘浓度检测电路,并通过粉尘风硐实验对其检测精度做了对比实验。实验结果表明,电荷感应式浓度传感器对金属粉尘的连续检测更加准确有效。

Research on Metal Dust Concentration Detection Technology

The floating combustible metal dust in polishing working places is explosive and so it is very important to detect the concentration of the dust .On the basis of the analysis of the dust concentration in the two main detection methods of light scattering and charge induction detection principles ,it is designed the corresponding dust concentration detection circuits , and through dust wind tunnel experiments ,the measurement accuracy is contrasted .The experimental results show that the continuous detection of the metal dust is more accurate and effective by charge induction density sensor .
