    • An electrode assembly for a particulate matter sensor in a gas environment. The electrode assembly includes an insulating tube, a conductor, and a positioning structure. The insulating tube has an outer surface and defines an interior cavity with an interior surface. The conductor is disposed within the interior cavity of the insulating tube. The conductor is electrically coupled to an electrode at a first end of the insulating tube and includes a contact portion at a second end of the insulating tube for connection to an external conductor. The positioning structure is coupled to the conductor. The positioning structure mechanically supports the conductor at a distance from the interior surface of the insulating tube to at least partially define an air dielectric gap at approximately a heater location corresponding to a heater. The positioning structure has an outer diameter approximately equal to an inner diameter of the insulating tube and has an inner diameter approximately equal to an outer diameter of the conductor.
    • 一种用于气体环境中的颗粒物质传感器的电极组件。 电极组件包括绝缘管,导体和定位结构。 绝缘管具有外表面并限定具有内表面的内腔。 导体设置在绝缘管的内腔内。 导体在绝缘管的第一端处电耦合到电极,并且在绝缘管的第二端处包括用于连接到外部导体的接触部分。 定位结构耦合到导体。 该定位结构将导体机械地支撑在离绝缘管的内表面一定距离处的导体,以至少部分地在对应于加热器的加热器位置限定一个空气电介质间隙。 定位结构的外径大致等于绝缘管的内径,其内径大致等于导体的外径。
