LSU ETAS LAMBDA
The AWS2 signal conditioning unit is used in conjunction with the Robert Bosch LSU broadband lambda sensor to evaluate the sensor signal. The AWS2 signal conditioning unit can be used for the following as an inexpensive alternative to the precision measuring instrument LA4: evaluating the LSU sensor signal in engine ECUs continuous measurements to determine sensor accuracy map optimization. The LSU sensor is fitted in the exhaust system as a measuring sensor (possibly in addition to a lambda sensor which has already been installed). The signal conditioning unit AWS2 is used to determine the pump current of the sensor and the current sensor internal resistance. The signal conditioning unit can be operated with various model ranges of the LSU lambda sensor; different sensor internal resistances must be set on the unit for this purpose. The unit is also designed to facilitate upgrading to ensure that it can be used with all future model ranges.
