    摘要: A photoacoustic gas sensor includes a photoacoustic cell configured to receive a gas mixture having a first gas component and a second gas component. The photoacoustic gas sensor also includes a light source configured to provide light to the photoacoustic cell. The photoacoustic gas sensor further includes a photoacoustic cell controller configured to measure a concentration of the second gas component using a speed of sound through the gas mixture, where the speed of sound is determined based on an absorption associated with the first gas component. In addition, the photoacoustic gas sensor could include a temperature sensor configured to measure a temperature of the gas mixture, where the photoacoustic cell controller is configured to determine the concentration of the second gas component using the speed of sound and the temperature.

    摘要: A system for testing and calibrating gas sensors with gas stored in a strip of packets. The strip may be fed into a chamber having a defined volume of air. A packet may be punctured with a mechanism to release one or more gases into the volume of air to result in an air-gas mixture. New air may be moved into the chamber to push the mixture out of the chamber to a sensor for testing and/or calibration. Then another packet may be punctured to release one or more gases into the volume of new air in the chamber for another air-gas mixture. This mixture may be moved out of the chamber, in the same manner as the previous mixture, to another sensor for testing and/or calibration. This procedure may be repeated with additional packets on the strip.
