1、 12 Dec. 08 motorsport1/2Lambda Sensor LSU 4.2This sensor is designed to measure theoxygen content and Lambda value ofexhaust gases in automotive engines(gasoline or Diesel.The wide band lambda sensor LSU 4.2 is aplanar ZrO2 dual cell limiting currentsensor with integrated heater. Itsmonotonic outpu

2、t signal in the range of = 0.65 to air makes the LSU capable ofbeing used as an universal sensor for = 1 measurement as well as for otherLambda ranges. The connector modulecontains a trimming resistor, whichdefines the characteristic of the sensor.The LSU operates only in combinationwith a special L

7、ermissible temperature. Install at a point where the gas is as hot as possible.Observe the maximum permissible temperature. As far as possible install the sensor vertically (cable upwards.The sensor is not to be fitted near to the exhaust pipe outlet, so that the influence of the outside air can be ruled out.The exhaust-gas passage opposite the sensor must be free of leaks in order to avoid the effects of leak-air.Protect the sensor against condensation water. The sensor is not to be painted, nor is wax to be applied or any other forms of treatment. Use only the recommended grease for lubri
