ABSTRACT:
To permit the use of molten glass in a sensor which has excellent characteristics with respect to capability of being melt-connected to a housing (11) while being pressure-resistant, a glass plug (12) is melt-connected to the housing (11) at a point remote from the end facing the combustion chamber; a quartz-glass rod (13), maintained in centered positioned in the housing by a powder or pulverized filling (15) of talcum, graphite, or spinel, is retained in the housing by a retention sleeve (16) pressing against a sealing O-ring (17); a bulge (13a) additionally contributes to maintaining the quartz-glass rod in position, and a spring washer (19) may be used, interposed between the quartz-glass rod (13) and the melted-in window (12) to accommodate differential expansion, under heating, of the filler (15) and the housing (11).
