| Abstract: | Measuring the temperature of heated cigarettes is crucial for ensuring consistent smoke characteristics and a satisfactory smoking experience. This study addresses the challenge of measuring temperature in small, sophisticated devices by creating a high-applicability, highly repeatable, and heat-resistant thermometer for cigarette heating elements. The device takes into account the distinctive structure of heating elements and uses high-precision equipment for multi-channel temperature detection. It also employs dry well furnaces for traceability, ensuring accurate and reliable measurement. Experimental results have shown that the thermometer has excellent gradient stability and up to ±1°C repeatability. Additionally, the device can perform multi-point multi-group temperature measurements, enabling it to accurately capture the temperature distribution within heated cigarettes. The device's heat resistance, repeatability, and stability make it an essential tool for optimizing heated cigarette processes. Its ability to improve the quality of heated cigarettes and reduce development costs significantly contributes to the industry's technological progress and economic benefits. This study has significant implications for the technical advancement and industrial development of the heated cigarette industry. |
