Abstract

To simplify manufacture and assembly of a temperature-compensated titanium dioxide oxygen sensor, the sensor (9, 9') is applied as a layer on the thermistor body (1), with an electrode (8) interposed; preferably, the thermistor body is densely sintered titanium dioxide, in the form of a closed tube (1, 1') which may have a central opening (FIG. 1: 2) therethrough, with the sensor body being porous titanium dioxide and located either on the inside (FIG. 1) surface of the thermistor body (1) or on the outside (FIG. 2) surface, and supported by the thermistor body, which forms the substrate and support surface for the sensor body.
