Acoustic measurement of gas temperatures
The efficiency of many processes in chemical, thermal and process engineering is determined by gas temperatures. In order to optimise these processes by means of closed-loop controls, the gas temperature needs to be measured promptly and precisely. The “classical” thermo couple method reaches thermal equilibrium with the gas to be measured with a long delay and is interferred by heat radiating surfaces.
In contrast, the speed of sound in gases depends on the gas temperature only. The newly developed ceramic sensing element measures the speed of sound in gas quickly and very precisely, and thus directly determines the gas temperature with the same accuracy and high speed (500—1 000 msec).
