    • A new apparatus for monitoring fine particle concentration in an exhaust system of a combustion engine has a part that extends into the exhaust system, and a housing that includes structure that attaches and seals the apparatus to the exhaust system through a single opening in a wall of the exhaust system. A gas inlet in the housing provides a measurement flow into a particle measurement sensor inside the housing. At least a fraction of the particles entering the particle measurement sensor are charged, and at least a fraction of the current carried by the charged particles are detected. A gas outlet in the housing carries the measurement flow away from the particle measurement sensor. The structure that attaches the apparatus to the exhaust system has one electrical connector that provides power to the sensor, and another electrical connector that transmits the electrical signal created by the sensor.
    • 用于监测内燃机排气系统中的细粒子浓度的新装置具有延伸到排气系统中的部分,以及壳体,其包括通过单独的开口将装置附接并密封到排气系统的结构, 排气系统。 壳体中的气体入口提供了到壳体内的颗粒测量传感器的测量流量。 进入颗粒测量传感器的至少一部分颗粒被充电,并且检测由带电粒子携带的电流的至少一部分。 壳体中的气体出口将测量流离开粒子测量传感器。 将装置附接到排气系统的结构具有向传感器提供电力的一个电连接器和传递由传感器产生的电信号的另一个电连接器。
