A particulate detection system for detecting the quantity of particulates contained in a gas under measurement flowing through a gas flow pipe, comprising: a detection section suitable to be attached to a gas flow pipe and to come into contact with the gas under measurement; a compressed air source which includes a compressor for producing compressed air and for supplying the compressed air to the detection section, wherein the detection section comprises: a space forming member which forms an internal space into which the gas under measurement is introduced, and a gas injecting source which is located adjacent to the internal space, comprising an injecting hole for injecting the compressed air supplied from the compressed air source toward the internal space; characterized in that it comprises: - a compressor drive circuit configured to drive the compressor under a first drive condition under which the compressed air is injected from the injecting hole with a first flow rate and under a second drive condition under which the compressed air is injected from the injecting hole with a second flow rate, the second flow rate being lower than the first flow rate and being different from zero 1/s, and - control means configured to control the compressor drive circuit, wherein the control means is configured to send a first instruction for instructing the compressor drive circuit to drive the compressor under the first drive condition when the detection section is operating, and to send a second instruction for instructing the compressor drive circuit to drive the compressor under the second drive condition when the detection section is not operating. a detection section suitable to be attached to a gas flow pipe and to come into contact with the gas under measurement; a compressed air source which includes a compressor for producing compressed air and for supplying the compressed air to the detection section, wherein the detection section comprises: a space forming member which forms an internal space into which the gas under measurement is introduced, and a gas injecting source which is located adjacent to the internal space, comprising an injecting hole for injecting the compressed air supplied from the compressed air source toward the internal space; a space forming member which forms an internal space into which the gas under measurement is introduced, and a gas injecting source which is located adjacent to the internal space, comprising an injecting hole for injecting the compressed air supplied from the compressed air source toward the internal space; - a compressor drive circuit configured to drive the compressor under a first drive condition under which the compressed air is injected from the injecting hole with a first flow rate and under a second drive condition under which the compressed air is injected from the injecting hole with a second flow rate, the second flow rate being lower than the first flow rate and being different from zero 1/s, and - control means configured to control the compressor drive circuit, wherein the control means is configured to send a first instruction for instructing the compressor drive circuit to drive the compressor under the first drive condition when the detection section is operating, and to send a second instruction for instructing the compressor drive circuit to drive the compressor under the second drive condition when the detection section is not operating.
