ABSTRACT:
A binary gas analyzer instrument and analysis method for determining percent composition of a cooling gas within a turbine generator is disclosed. The instrument includes a measurement block having a plurality of cells therein, some of which comprise sealed cells containing a known reference gas. One of the cells comprises a measurement cell and contains the binary gas mixture to be evaluated. Each of the cells contains a thermistor and a heater is provided for keeping the cells at a substantially constant temperature. An electric current supply provides a constant current to each thermistor for selfheating, and the gas within each cell conducts heat away from the thermistor at a distinctive rate. Measuring apparatus is selectably connectable across each cell thermistor to measure the voltage drop across said thermistors, and computational apparatus is provided to automatically translate the measured voltage drop across the measurement cell thermistor into a percent compositional reading of the binary gas constituents. Translation is accomplished by the computational apparatus with reference to the voltage drop across at least one of the reference cell thermistors.
