8.4 Micro-controller unit and PC Software

The microcontroller unit (MCU) contains all components for signal processing and control
sequencing. It is working under the control of the PC software, collecting and processing signals
and sending data to the PC-software. The communication between MCU and PC is taking place
via USB interface.
The first stage of signal processing in the PC is the linearization. This is necessary because the
output signal of the IR cells as a function of the sample gas concentration have an exponential
characteristic.
The linearization produces a correction which is exactly opposite to the characteristic of the
detector, so that a linearized analysis signal is available.
The second stage is integration. It starts at the beginning of the combustion and it ends after a
pre-set minimum time. In case the combustion takes longer, the integration is prolonged. Then,
the detector signal is compared to a comparator level. The integration continues as long as the
IR-output signal is higher than the comparator level. When it comes down below this level, the
integration is stopped. Should the IR-signal remain above the comparator level, the analysis is
interrupted by a set maximum time. Then the integration is terminated.
The integrated value is directly proportional to the SO

2

resp. CO

2

content in the combustion

gases. The blank value is deducted from the integrated value.
The integrated value is then multiplied by the calibration factor. After dividing by the sample
weight, a result is obtained which does not depend on the sample weight.
With the multipoint calibration the results can be calculated to match exactly the values of
certified standard materials.
Finally the results are directly shown as % S or % C on the PC screen.
For instructions of operating the PC-software, please refer to the Help-function of the Software.
