911 Fuel and ignition system 2 2469/2473 Oxygen sensor (LSF) Special characteristics of the new oxygen sensor The planar oxygen sensor LSF is a further development of the heated oxygen sensor ? Brief on-times of oxygen sensing LSH. It equates functionally to the heated ? Stable regulating characteristics oxygen sensor (Lambda probe) with a step ? Low heating power demand map at Lambda 1. Unlike the LSH, on the ? Quickly operational oxygen sensor LSF the solid-state electro- ? Small overall size, low weight lyte is made up of ceramic sheets. The oxy- gen sensors up and downstream of the The sensor element of the planar oxygen catalytic converter have different part nu m- sensor is made up of ceramic sheets and bers. has the form of a rectangular wafer with rectangular cross section. The individual function layers (electrodes, protective la y- ers, etc.), are produced with screen printing technique. The laminating of various printed sheets on top of each other allows for a heater to be integrated in the sensor element. 2_11_02 Design of the planar oxygen sensor (Lambda probe) 1 – Exhaust gas 2_10_02 2 – Reference air channel 3 – Heating element 1 - Connection cable Us – Voltage of oxygen sensor 2 - Protective sleeve 3 - Planar sensor element (ceramic sheets) 4 - Ceramic supporting tube 5 - Sensor housing 6 - Ceramic sealing pack 7 - Protective tube 2002 Service Information 2 - 9
