Lambda Sensor LSU 4 - Bosch Motorsport

1 Bosch Motorsport | Lambda Sensor LSU Sensor LSU uApplication: Lambda to uWide banduExhaust gas temperature range (max.) for short time<1,030 CuMax. Hexagon temperature 570 CThis Sensor is designed to measure the proportion ofoxygen in exhaust gases of automotive gasoline wide band Lambda Sensor LSU is a planar ZrO2dual cell limiting current Sensor with integrated heat-er. Its monotonic output signal in the range of to air makes the LSU capable of being used as auniversal Sensor for Lambda 1 measurement as well asfor other Lambda ranges. The connector module con-tains a trimming resistor, which defines the character-istic of the main benefit of the LSU is the very robust designcombined with the high Bosch production Lambda Sensor operates only in combination witha special LSU-IC, used in most Bosch Motorsport ECUsand Lambda control units like LT4.
