Publication number: 20230114548Abstract: A measurement system (100) determines gas concentrations in a gas mixture of a gas sample by utilizing thermal conductivities and paramagnetic effects of thermal conductivities in the gas mixture involving data sets (203). A circuit arrangement provides measured values with an AC signal component and with a DC signal component to a calculation and control unit (200). An oxygen concentration in the gas mixture of the gas sample is determined based on the standardized AC signal components and a concentration of another gas in the gas mixture of the gas sample is determined based on the standardized DC voltage signal components. Output signals are generated by the calculation and control unit, which indicate the determined oxygen concentration and the determined concentration of another gas in the gas mixture of the gas sample.Type: ApplicationFiled: October 5, 2022Publication date: April 13, 2023Inventors: Hartmut STARK, Günter STEINERT, Hans-Ullrich HANSMANN, Tobias HEISE, Robert JAHNS

Patent number: 11154216Abstract: A device (1) for determining the concentration of a gas component is configured with a radiation source (30) for radiating (31) light as a light emission in an infrared wavelength range. Two detector arrays (52, 62) with two detector elements (50, 60) are configured suitably for detecting the light emission generated by the radiation source (30) in two detector arrays (52, 62). Two filter elements (51, 61) are associated with the detector elements (50, 60). The two detector elements (50, 60) are oriented in relation to the radiation source, so that a range of overlap (65) is obtained due to the two detector arrays (52, 62). The range of overlap (65) causes attenuations in the propagation of light, which may be due to gas molecules or moisture (400). The attenuations in the propagation of light affect both detector elements (50, 60) and are compensated concerning the determination of the concentration.Type: GrantFiled: October 27, 2017Date of Patent: October 26, 2021Assignee: Drägerwerk AG & Co.

Patent number: 10502682Abstract: A device (1) for determining the concentration of a gas component is configured with a radiation source (30) for emitting (31) a light radiation or heat radiation in an infrared wavelength range. A detector array (40) has at least two detector elements (50, 60), configured to detect the radiation generated by the radiation source (30), in an angular arrangement (52, 62) and with filter elements (51, 61). At least one of the two detector elements (50, 60) is oriented in an angular arrangement (52, 62) in relation to a vertical axis (32), so that a range of overlap (65) is obtained due to the angular arrangements (52, 62). The range of overlap (65) causes attenuations in the propagation of light, which attenuations may be due, for example, to gas molecules or moisture (400), affect both detector elements (50, 60) and are thus compensated concerning the concentration determination.Type: GrantFiled: October 27, 2017Date of Patent: December 10, 2019Assignee: Drägerwerk AG & Co.
