Page 6: Principle Of Measurement
Cross-sensitivity is the sensitivity of the measurement on other gases than the measured component. The FTC320-OEM contains a TC sensor that analyzes the quantitative composition of gas mixtures. The measurement is based on the heat transfer between a heat source and a heat... - Page 7 File name: 1.09KD221202EMAV01 Figure 1: Schematic drawing of thermal conductivity measurement. The sensor is mounted in the stainless steel block that is kept at a constant temperature. sink. The measuring gas is led through a stainless steel block that is kept at a constant temperature of 63 C (for most applications).
