This sensor is designed to measure the proportion of oxygen in exhaust gases of automotive engines (gasolineor Diesel). A version with a protection tube of Inconel for pre-turbo (supercharger) mounting is available.The wide band lambda sensor LSU ADV is a planar ZrO2 dual cell limiting current sensor with integrated heater. Its monotonic output signal in the range of lambda 0.65 to air makes the LSU ADV capable of being used as a universal sensor for lambda 1 measurement as well as for other lambda ranges.The LSU ADV has no trimming resistor inside the connector what results in just 5 connector pins. Compared to LSU 4.9, the LSU ADV has a wider working temperature range.LSU ADV operates only in combination with a special evaluation unit used in lambda control unit LT4 ADV.You’ll find this unit and more on our homepage at Electronics/Sensor Interfaces.
