| Abstract: | Application of charge induction method in dust concentration measuring is introduced,and measurement method of characterizing dust concentration by inductive voltage of sensor in alternating electric field is put forward,and a theoretical derivation is given.On these basis,a cylindrical sensor is designed,and build up test platform for concentration detection,and carry out study of simulation test.The result of the experiment indicates that in a certain situation when the dust concentration ranges between 0.81 g/m3 and 1.99 g/m3,the device is able to be applied to test dust concentration,which the average error of measurement value and actual value is 1.8 ％. |
