This sensor is designed to measure the proportion of
oxygen in exhaust gases of automotive engines (gaso-
line or Diesel). A version with a protection tube of In-
conel for pre-turbo-(supercharger) mounting is available.
The wide band lambda sensor LSU ADV is a planar
ZrO 2 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 be-
ing used as a universal sensor for lambda 1 measure-
ment as well as for other lambda ranges.
The LSU ADV has no trimming resistor inside the con-
nector what results in just 5 connector pins. Com-
pared to LSU 4.9, the LSU ADV has a wider working
LSU ADV operates only in combination with a special
evaluation unit used in lambda control unit LT4 ADV.
