Test report for measurement of performance vs temperature of Whittaker Electrochemical Cell

摘要

This document is the test report that summarizes the results of the tests on the Whittaker cells between the temperatures of -20(degrees)F and +120(degrees)F. These sensors are used on the Rotary Mode Core Sampling (RMCS) flammable gas interlock (FGI), to detect and quantify hydrogen gas. The test consisted of operating five Whittaker electrochemical cells in an environmental chamber that was varied in temperature from -20(degrees)F to +120(degrees)F. As the rate rise of the voltage from the cells changed, after exposure to a gas concentration of 1% hydrogen at the different temperatures, the voltage was recorded on a computer controlled data acquisition system. Analysis of the data was made to determine if the cells maximum output voltages and rise times were effected by temperature.
