Operating Principles

The charge transfer of fine particles such as dust flowing across a pipe or airflue is applied to static induction and detected by the noncontact sensor. This signal is measured and converted into an alternating-current response. The friction current produced when particles directly hit the probe is cut and this realizes stable output through the special circuit.
