    • An electrochemical gas sensor with a stacked arrangement of electrodes and nonwoven layers arranged in parallel, comprising at least one measuring electrode (3) and at least one counterelectrode (5). A porous membrane (8) that is permeable to air is in contact with the stacked arrangement of electrodes and nonwoven layers arranged in parallel at least on one side, at least one layer of a hydrophilic nonwoven (7) is located between the electrodes. The porous membrane (8) that is permeable to air and the hydrophilic nonwoven (7) extend into a separate equalization volume (9), which is filled with electrolyte at least partially and is located at least partially in one plane with the electrodes. The separate equalization volume (9) surrounds the electrode arrangement at least partially in this plane, and the porous membrane (8) that is permeable to air is exposed to ambient pressure at least in partial areas. Such sensors are characterized by a flat shape, high insensitivity to shocks, independence from the position, and high tolerance to variations in environmental humidity.
    • 一种电化学气体传感器,其具有并联布置的电极和非织造层的堆叠布置,包括至少一个测量电极(3)和至少一个反电极(5)。 可渗透空气的多孔膜(8)与至少在一侧平行布置的电极和非织造层的堆叠布置接触,至少一层亲水性无纺布(7)位于电极之间。 可渗透空气的多孔膜(8)和亲水性无纺布(7)延伸到独立的均衡体积(9)中,其中至少部分地填充有电解质并且至少部分地与电极位于一个平面中。 分离的均衡体积(9)至少部分地围绕电极装置在该平面中,并且可渗透空气的多孔膜(8)至少在部分区域暴露于环境压力。 这种传感器的特征在于平坦的形状,对冲击的高度不敏感性,与位置的独立性以及对环境湿度变化的高耐受性。
