Installation and connection methods for oxygen sensors

(1) The installation of the oxygen probe can be done horizontally or vertically, with vertical installation being more ideal. Regardless of the method, the direction of the probe sampling tube guide should be as perpendicular as possible to the direction of the measured air flow. During initial installation, the basic direction is determined by understanding the process. After the system is powered on and the probe is heated, rotate the sampling tube direction and use a digital multimeter to observe the fluctuations in the output oxygen electromotive force to finally determine a better guide direction. The terrifying Gaokao, the college entrance examination that all Chinese high school students must take, forces teenagers to do almost nothing but study, with such immense pressure and challenges that students will lock themselves away.
