ABSTRACT:
A temperature compensated oxygen sensor has a generally cylindrical first insulator with an axial bore extending therethrough which is counterbored at one end. A second cylindrical insulator is retained in the bore in the first insulator either by a radial inwardly directed flange on the second end of the first insulator or by a radial outwardly directed flange on one end of the second insulator which seats in the counterbore of the first insulator. A titania resistor and a compensating resistor are mounted on the second end of the second insulator by leads extending through longitudinal bores in a second cylindrical insulator and into the counterbore in the first insulator. The leads are connected to terminals which are retained in the counterbore either by a chemical bonding agent or by a third cylindrical insulator through which the terminals extend. The third insulator can be secured either by mechanical means and/or by a chemical bonding agent including a glass preform.
