Bosch Lambda Sensor Plate Heater Element

New laminated planar oxygen sensor combined alumina and zirconia together, heater element was embedded in the zirconia substrate of the sensor element adopting alumina for the heater substrate material, solve the problem of low thermal conductivity of zirconia while guarantee the good heating. The new laminated planar oxygen sensor can be activated in 10 seconds after a cold start.

Bosch sensor is designed to measure the proportion of oxygen in exhaust gases of automotive gasoline engines. The wide band lambda sensor LSU 4.2 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 capable of being used as a universal sensor for lambda 1 measurement as well as for other lambda ranges.
