  • Publication number: 20250049137
    Abstract: An aerosol delivery device is provided that comprises a housing equipped with a heating element, a resistance temperature detector (RTD) and a control component. The housing may contain an aerosol precursor composition, and the heating element may be controllable to activate and vaporize components of the aerosol precursor composition. The RTD may have a resistance that is variable and proportional to a temperature of the heating element, and may also have a temperature coefficient of resistance that is suitably large enough and invariable with respect to the temperature of the heating element. The control component may be configured to measure the resistance of the RTD and therefrom determine the temperature of the heating element, and control at least one functional element in real time based on the temperature so determined, including output of the temperature for presentation by a display, or adjustment of the power to the heating element.
