Abstract

A particulate detection system () for detecting the amount of particulates S in a gas under measurement EG includes a detection section (), a drive circuit (), and a drive control section (). The detection section includes a first potential member () maintained at a first potential PV, a second potential member () maintained at a second potential PVE, PV, and an insulating member () disposed between the first and second potential members. The system includes insulation test means (, S, S) for testing the degree of insulation between the first and second potential members. The drive control section includes drive permission/prohibition determination means S, Sfor determining, on the basis of the degree of insulation tested by the insulation test means, whether to permit the drive of the detection section by the drive circuit.
