In an oxygen analyzer for an industrial process, an automotive type oxygen sensor has a sensor element assembly with an outer thin walled shield containing insulation and surrounding the sensor element of the automotive type oxygen sensor.

An industrial process oxygen analyzer, and method of using same, incorporates an automotive oxygen sensor to minimize the criticalness of controlling heater temperature during operation. Higher sensor heater temperature, required to accommodate the automotive oxygen sensor, is achieved by application of higher supply voltage to the sensor heater. Current limiting of the heater supply circuit reduces stress on the sensor heater, even at the higher operating temperature.
