METHOD AND APPARATUS FOR MEASURING THE O2 CONTENT OF A GAS ABSTRACT A method and apparatus for obtaining an electrical signal which is a function of the O2 content of the exhaust gas of an internal combustion engine. Two resistors (1 and 3) are exposed to the exhaust gas of an internal combustion engine. Both resistors (1 and 3) have a resistance which varies as a function of the temperature of the exhaust gas to which it is exposed. However, the resistance of one of the resistors (1) also varies as a function of the oxygen content in the exhaust gas. Therefore, by applying a voltage to the resistors an electrical signal can be obtained which is a function of the O2 content of the exhaust gas, with the temperature effect of the exhaust gas on the network output being minimized or eliminated. The resistors (1 and 3) that form the sensing element (10) are connected in series with other resistors to form a first and second resistor network which is connected together in parallel circuit relationship.
