Abstract
The sensitivity of a membrane-covered oxygen gas sensor under the influence of gas flow has been tested experimentally. As the oxygen sensor is placed in different positions relative to the air-pump and gas flow meter, the effect of gas flow-rate on the response of the sensor is notable. By choosing appropriate connective modes, the Clark-type sensor may be made insensitive to the gas flow-rate. This sensitivity to flow results from the change in gas pressure in the sensor gas chamber. The relationship between the sensor response and the gas flow-rate is discussed.
