BOSCH氧传感器LSU4.9

博世LSU4.9氧传感器英文详细说明书， The wide band lambda sensor LSU is a planar ZrO2 dual cell limiting current sensor with an integrated heater. It is used to measure the oxygen content and the λ-value of exhaust gases in automotive engines (gasoline and diesel). Its monotonic output signal in the range of λ=0.65 to air makes the LSU capable of being used as an universal sensor for λ=1 measurement as well as for other λ ranges. The connector module contains a trimming resistor, which defines the characteristics of the sensor and is necessary for the sensor function. The wide band sensor LSU operates only in combination with a special LSU control unit (e.g. AWS control box, LA4 or CJ125 IC).
