Abstract: |
A precise heating temperature control device and method without temperature sensor are disclosed that belongs to temperature measuring technique field, the characteristics are those: the controller obtains the practical temperature by measuring the resistance of the heating elements, when the practical temperature is lower than the target temperature, and the heating elements are pulse heated, and the practical temperature of heating elements are controlled at allowed extent. The invention does not need the additional temperature sensor and the resistance matched with the bridge, and it has simple structure, low cost, and accurate control temperature, and it can be used in any occasion that the temperature control is realized by resistance hater. |
