Patent ID: 10401273

Abstract:
A particle detection system (1) includes a particle sensor (10) having a detection section (11) exposed to a gas under measurement EG. The particle sensor (10) includes an insulating member (121, 100), and a heater section (150, 105) for heating at least a portion of the gas contact surface (121s, 101s) of the insulating member (121, 100). The particle detection system (1) includes adhesive restraining energization means (225, 223, S4, S10) for heating the gas contact surface (121s, 101s) to an adhesion restraining temperature Td at which adhesion of the particles S to the gas contact surface (121s, 101s) is restrained as compared with the case where the heater section is not energized, wherein adhering particles SA which are particles adhering to the gas contact surface (121s, 101s) burn at the particle burning temperature Tb.
