The Lambda Measurement Modules LA4 and AWS2 facilitate the acquisition of the characteristic mixture formation variables of oxygen content, air/fuel ratio, and lambda. The modules are connected to Bosch LSU broadband λ-probes, which are installed in the exhaust system as a measurement sensor.
The devices are able to monitor λ values greater or smaller than one in a wide measurement range. They are suited for the development and testing of lambda controls of diesel engines and of lean concepts for gasoline and gas engines.
The Lambda Measurement Modules are deployed in the laboratory, at the test bench and in the vehicle. In standalone usage they are suited for all kind of lambda monitoring applications.
The LA4 Lambda Meter can be used either standalone or as a measuring device in a calibration environment. By its integration within INCA, the LA4 Lambda Meter is a versatile device for testing and calibrating the lambda control of an ECU.
The AWS2 Signal Conditioning Unit is a cost-effective alternative to the high-precision Lambda Meter LA4. The AWS2 analyzer circuit outputs the pump current of the sensor and the internal resistance of the sensor, which depends on its temperature, in terms of voltages.
