Development of an Infrared Absorption Transducer to Monitor Partial Pressure of Carbon Dioxide for Space Applications 932145
An Infrared (IR) carbon dioxide (CO2) transducer has been designed, developed, and produced for space applications. This transducer provides measurement of partial pressure of CO2 in life support applications, including the Extravehicular Mobility Unit (EMU), Space Shuttle Orbiter and Spacehab. The electrochemical sensor presently used for these applications has a slow response time and has reliability concerns due to the electrolyte. The new microprocessor based unit has a fast response time and can be tailored to other space applications.
