Computer Measurement System for Gas Temperature Field of Ai Tiao Combustion Cone

Moxa stick has been widely applied in moxibustion therapy in the field of overall health. The temperature field of the combustion cone of moxa stick is important parameter for clinical efficacy and processing technology. Due to wide temperature range and violent oxidation-reduction atmosphere, the measurement of the inner gas phase temperature has no suitable commercialized instruments. Computer measurement system for gas temperature field of combustion cone of moxa sticks is designed and manufactured. Advanced thermocouple sensors, integrated circuits and software technology were used in this testing system. The data acquisition system uses a 16 bit high-precision high-speed A/D conversion chip, which has an accuracy one order of magnitude higher than existing technologies and a speed more than twice as fast. It realizes the automatic collection of temperature data by the software while starting sucking. This system is equipped with data processing software, which can automatically analyze and provide contour maps of the gas phase temperature distribution inside the cigarette at any given time. The system is easy to operate and has good stability. The temperature sensor has good durability, which can ensure the repeatability of the experiment and save costs.
