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 / m3and 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 %.
