  • Page 51: Mounting Position Of Sensing Element

    When mounting the sensing element after the catalytic converter, make sure that no material es- capes from the catalytic converter. The possible tilt angles of the sensing element depend on the course of the exhaust pipe. Mounting in a vertical exhaust pipe is not recommended by MOTORTECH. Rev. 06/2021...
  • Page 52 6 Installation Instruction Tilt angles horizontal exhaust pipe Exhaust gas flow Tilt angles vertical exhaust pipe The sensing element heats up as soon as the NO sensor is powered. Therefore, the sensing ele- ment must be installed on the exhaust pipe at a suitable location at which people at the plant cannot be burned by it, or an appropriate protection must be installed around the sensing ele- ment that prevents contact with it.
