Abstract : The patent describes an infrared analyzer cell having at least two pockets of the same gas separated by a very thin sensitive diaphragm, an electrical element to function with the diaphragm as a capacitor, a slow leak path between the pockets to preclude static pressure differential across the diaphragm, and an infrared window. The centroids of the two gas pockets are contiguous to minimize deflection of the diaphragm relative to the pockets of gas with vibration of the cell.
