The analyser functions on the principle of heat reaction.The difference in temperatures at the reference measuring point and the measuring point, is a directly-dependent variable of the component part of combustible substances in the gas. The reference measuring point is subjected to the heated non-burned gas mixture, whilst the second probe of the thermocouple pile measures the temperature of the burned gas. A load-independent current of 0-(4)-20 mA is available for connection to electric test meters, plotters and limit value monitors. An RS 232 interface is incorporated for data communication.
The inclusion of a measured value integration provides the facility of forming the average value of measured quantities, continuously or over a prescribed period of time.
