This sensor comprises: a sensor element (2) with a sensor area (21), a housing (4) that supports said sensor element (2); an inner protective cover (31) that covers the sensor area (21) and that contains openings (312, 314) for the circulation of the gas to be measured; a middle protective cover (32) that concentrically covers said inner protective cover (31) and that contains openings (322, 324) for the circulation of the gas to be measured; and an external protective covering (33) that concentrically covers said middle protective cover (32). The inner and middle protective covers (31) and (32) comprise, each, three tabs (316, 326) alternately coupled in six openings (337) of the external protective cover (33). Said tabs are joined by means of a circumferential weld (5) to a peripheral rib on the housing (4) where said tabs (316, 326) and said openings (337) are accommodated. |
