Bosch LSU ADV Wideband Lambda Sensor

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 which results in just 5 connector pins. Compared to LSU 4.9, the LSU ADV has a wider working temperature range.
