Stead of ETAS LA4 Lambda Meters The ES630/ES635 (one channel) and ES631/ES636 (two channel) Lambda Modules support the Bosch manufactured wideband oxygen sensors, including the Bosch LSU ADV sensor with extended measurement range and fast response, the lean-burn oxygen sensor Bosch.

Above is our CAN bus version,. CAN bus communication is the widely used data exchange method in the automotive industries. This is the professional way for automotive control systems, especially an engine control unit (ECU), to get the Lambda / O2 concentration from the wideband controller. CAN bus communication eliminates the DAC (Digital to Analog Converter) and then ADC (Analog to Digital Converter) conversions, and therefore eliminates 2 big error sources, and keeps the original signal accuracy. Compared to the CAN bus, 0-5V analog output is an amateur method. Below is an OEM version of the ALM,. It is a mini-circuit board that can be easily built into any OEM controller.
The board size is 2.5'X1'x0.5'. It has its own LSU sensor connector, it gets the power from the main controller. It feeds back the Lambda or O2% to the main controller, either via 0-5V or CAN bus, or serial communication, at your option.
We now offer a wideband controller dedicated to diesel engines,. This is the only wideband controller you can find in the world that supports the LSU4.9D sensors.

For years people have been wrongly told that LSU4.9 sensors are for diesel engines, and LSU4.2 sensors for gasoline sensors. And they don't know there is a diesel version the LSU4.9 sensor, LSU4.9D. Now we know LSU4.9 sensor is primarily for gasoline engines though it also works fine with a diesel engine. LSU4.9D is the one solely designed for diesel engines and it runs the best with regarding to the diesel soot environment.
Below you can see the comparison of the 3 LSU sensors, click it you will find the meaning of the difference. Yes, we take the credit card payment.
