  • Patent number: 12158446
    Abstract: 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.

  • Patent number: 9360441
    Abstract: A measurement head is provided for a device for measuring the concentration of at least one gas, in particular oxygen. A gas sample a measurement element (1) is arranged in the region of an opening on a circuit board (11). To convey gas a duct (16, 17) is formed in each of two metal bodies, which surround the measurement element (1) and serve as magnetic poles. During operation of the measurement head the gas sample flows substantially perpendicularly, first through one of the metal bodies (12, 13), and then through the opening (18) on a side of the measurement element (1) facing the opening and emerges again through the other metal body (14, 15).
