Fast Heating Polyimide Film Heater

Polyimide heating sheets are usually equipped with temperature sensors and temperature control circuits. The temperature sensor monitors the temperature of the heating sheet or the heated object in real time, and feedbacks the temperature signal to the temperature control circuit. The control circuit compares the set temperature value with the actual measured temperature, and controls the heating power by adjusting the current input to the heating sheet, so as to achieve accurate control of the temperature. For example, when the actual temperature is lower than the set temperature, the control circuit will increase the input current, so that the heating sheet generates more heat; When the actual temperature is higher than the set temperature, the control circuit reduces the current, reduces the heating power, and keeps the temperature within the set range.
