Abstract

PURPOSE: To produce the oxygen concentration measurement equipment of high reliability with good mass-productivity by using disc-like detecting element and spring pressure so as to seal the main body under pressure.
CONSTITUTION: The element 21 in which the electrode is formed in the electrolyte of disc shape is accommodated in the sheath 23 at an outer circumference of the inside of the bottom face of which the washer 27 made of platinum foil and at a center portion of a bottom face thereof, a vent hole 22 is provided and a can 25 is inserted into the outer circumference of the upper end under pressure and welded and fixed. The ring 26 made of stellite is inserted and thereafter the shaft 28 to which the platinum foil made washer 24 is welded is inserted to the lower end surface to contact the outer circumference portion of the disc shape element 21. Then, through the insulating cap 29 composed of stellite, the shaft 28 is pressed by using the spring made of heat resisting material to complete the contact of the washer 24, 27 of the signal drawing out terminal and the element 21.
