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 600 CThis Sensor is designed to measure the proportion ofoxygen in exhaust gases of automotive engines (gaso-line or Diesel).The 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 asa universal Sensor for Lambda 1 measurement as wellas for other Lambda ranges. The connector modulecontains a trimming resistor, which defines the charac-teristic of the main benefit of the LSU is the 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.
