Their data acquisition is automatically synchronized with other ETAS measurement modules. The Lambda Modules supply the measuring host PC simultaneously with values for various measured variables. Via Ethernet, the ES63x Lambda Modules can be connected directly to a PC with suitable measurement software or with other ETAS compact hardware modules. In addition, it is possible to output a linearized signal with voltage values in the range between 0 V and 10 V at an analog output. The display shows two measurement values and the operating mode at the same time. Grouped around the display, there are six control buttons, which can be used to configure the device and the display. By means of the external sensor, the pressure in the turbo charger can be measured.Īll module variants possess a display and can be used on their own. As an example, on the basis of an air pressure measurement, the height profile of a test drive can be recorded. Independently of lambda measuring, pressure signals are available for further analyses. Influences of atmospheric and exhaust pressure changes on the lambda measurement can automatically be compensated by the lambda modules. With this external sensor, pressure changes within the exhaust or air system can be measured. To the modules ES635 and ES636, an external pressure sensor can be connected in addition.

Measurement of atmospheric and exhaust pressureĪll ES63x modules are capable of measuring the atmospheric pressure by means of an integrated sensor. As an option, ES635 and ES636 modules can be connected to a pressure sensor mounted in the exhaust system. To compensate for pressure effects, all models provide a built-in sensor. Lambda Modules are connected to a wideband lambda oxygen sensor. The ES630/ES635 (1 channel) and ES631/ES636 (2 channels) Lambda Modules are connected to an LSU broadband lambda sensor.
