Principle

This thermal conductivity gas analyzer measures gas concentration by utilizing the difference of thermal conductivities between two gas components. In the detector, there are a reference chamber and a measuring chamber, in each of which a thin platinum wire is stretched. The reference chamber is filled with reference gas. The sample gas is flowed through the measuring chamber. Each platinum wire composes a bridge circuit in combination with an external fixed resistor, and is heated by flowing a constant current. When there is a change in the concentration of the component under measurement, the thermal conductivity of sample gas will change to affect the temperature of the platinum wire in the measuring chamber. The resulting thermal change is taken out as a change in electric resistance, according to which the concentration of measured gas is calculated.
