Термохимический газоанализатор повышенной чувствительности для систем контроля и управления сжиганием

Abstract

The approach permitting one to raise the accuracy of thermochemical gas analyzers at the expense of temperature changes in a soaking drum by their measuremetn with the use of a compensative unit operating as a renstance thermoelement is consid­ered. Theoretical and experimental studies of the proposed engineering resolution on the sensitivity and additional error in the temperature range up to 200 °C are outlined. Due to such an approach the lower threshold of measurement range in the ther­mochemical method approximates to a level of electrochemical resources of measurement.
