    • A measuring head for the determination of the concentration of a paramagnetic gas in a gas sample has first and second housing parts (21, 2) made of a steel alloy for accommodating a magnet coil body (4, 5) each. The magnet coil bodies extend concentrically around the central axis of each housing part (21, 2). Metallic bars (31, 3), which are used as magnet poles for the measuring head, are located at spaced locations with a defined air gap in the assembled state of the measuring head. The bars are arranged in the center of the measuring head in the area of the central axis of the housing parts (21, 2). A sample gas cuvette support (6) is provided in the air gap between the housing parts (21, 2) for positioning a sample gas cuvette holder (1). The sample gas cuvette support (6) is provided with a gas inlet and gas outlet (8, 81).
    • 用于确定气体样品中顺磁气体浓度的测量头具有由用于容纳磁体线圈体(4,5)的钢合金制成的第一和第二壳体部分(21,2)。 磁体线圈体围绕每个壳体部分21,2的中心轴线同心地延伸。 用作测量头磁极的金属棒(31,3)位于测量头组装状态下具有限定气隙的间隔位置。 这些杆在壳体部分(21,2)的中心轴线的区域中布置在测量头的中心。 在壳体部分(21,2)之间的空气间隙中设置样品气体比色皿支架(6),用于定位样品气体比色皿支架(1)。 样品气体反应杯支架(6)设置有气体入口和气体出口(8,81)。

    • A radial compressor is provided for respiration purposes. The sound emissions generated by deflections and separations of the gas flow in the compressor wheel and the housing of the radial compressor and by the high-speed motor of the radial compressor are reduced. This is achieved with a specially shaped passage channel (4) for the volume flow, which exerts a stabilizing effect on the volume flow utilizing the Bernoulli principle of flow. Additional sound reduction is provided by using a separate mass (8) arranged between the motor (6) and the housing (3), which absorbs the sound energy generated by the high-speed motor (6). Also sound reduction is provided by suspending the radial compressor with membranes in a closed capsule.
    • 提供径向压缩机用于呼吸目的。 通过压缩机叶轮和径向压缩机的壳体以及径向压缩机的高速电动机的气流的偏转和分离产生的声音减少。 这通过用于体积流量的特殊形状的通道(4)来实现,其使用伯努利流动原理对体积流动施加稳定作用。 通过使用布置在电动机(6)和壳体(3)之间的单独的质量(8)来提供附加的声音降低,其吸收由高速电动机(6)产生的声能。 通过将径向压缩机悬挂在封闭的胶囊中也可提供声音降低。
