1 Automotive Research & Development Diagram Diagram assistant System settings Combustion Analyzer Series The DEWETRON combustion analyzers are innovative systems for engine testing. The unit is very easy to operate due to Windows based applications, but still very powerful. Due to the integrated charge amplifiers, sensors (e.g. Kistler combustion sensor) can be connected directly to the combustion analyzers. The system can process (even existing) crankshaft signals (60-2) directly in the analysis part. The signal representation is made by an efficient real time display, which shows the data of up to 15 measurement channels. Beside the test specifications diagram and extensive statistics functions, the knocking recognition is a very important part, whose results can be transfered in real time to test bed systems. Using standard components makes the system ready for the easy maintenance and for future developments....the precision signal conditioning company
