摘要： A nebulizer determines the pressure and flow direction of the receiving gas for atomized liquid. A member of the apparatus is subjected to pressure exerted by the gas. The member is coupled to a bi-directional mechanical-electrical conversion element, such as a piezoelectric element, to form a pressure transducer. The member exerts a mechanical loading on the element responsive to the gas pressure to which it is subjected. In one embodiment, the element mechanically vibrates responsive to alternating electrical energization to discharge the liquid into the gas. The electrical admittance of the element is alterable by the mechanical loading applied to the element by the member. The difference between admittances measured in the loaded condition of the element and in an unloaded condition at the selected energization frequency is an indication of the pressure of the gas. By observing whether the magnitude of the admittance in the loaded state is greater or less than that in the unloaded state, the flow direction of the gas may also be determined. Or the flow direction may be determined by observing the changes in admittance as the frequency of the electrical energization is varied. In another embodiment, the piezoelectric element is not energized. The electrical output of the element, when subjected to a mechanical loading from the gas pressure, is used to detect gas pressures and/or as an indication of the gas pressure.

摘要： A non-dispersive single beam detection assembly in an infrared gas analyzer. The detection assembly comprises radiation source(s) providing infrared radiation, a measuring chamber, and a physical beam splitter for dividing said radiation beam into a reflected beam portion and a transmitted beam portion, or for combining a reflected beam portion and a transmitted beam portion into said radiation beam. A measuring detector receives one beam portions, and a reference detector receives another beam portion. Alternatively a measuring/reference detector receives both beam portions. Said transmitted beam portion has a first spectral intensity peak at shorter wavelengths with a first peak wavelength, and said reflected beam portion has a second spectral intensity peak at longer wavelengths with a second peak wavelength. There is a wavelength gap between said second peak wavelength and said first peak wavelength, which gap corresponds a wavelength shift of an optical interference filter with said second peak wavelength as tilted from its perpendicular position to an angled position. Said wavelength gap is at maximum 10% of the second peak wavelength, and at minimum 0.5% of the second peak wavelength.
