ABSTRACT:
A gas concentration sensor for use in a closed container having a constant volume and gas within the container, wherein the gas has a known pressure at a given temperature. The sensor includes a pressure sensing device disposed within the container, wherein the pressure sensing device generates a first electrical signal functionally related to the gas pressure within the container. The sensor also includes an electronic circuit connected to the pressure sensing device which amplifies the first electrical signal and produces a second electrical signal functionally related to the gas concentration within the volume at any temperature.
