Thin Flexible PCB Polyimide Heater with Ntc Thermistor Made in China

A polyimide heater with an NTC (Negative Temperature Coefficient) thermistor refers to a heating element made from polyimide material that includes an integrated NTC thermistor for temperature sensing and control purposes. This combination is commonly used to create a more sophisticated and precise heating system that can regulate its own temperature.

Here's how the polyimide heater with NTC thermistor typically works:

Polyimide Heater: The polyimide heater is a flexible heating element made from polyimide material. It generates heat when an electric current passes through it. It can be shaped and positioned to heat a specific area or object.

NTC Thermistor: The NTC thermistor is a temperature-sensitive resistor whose resistance decreases as the temperature increases. In other words, its resistance exhibits a negative temperature coefficient. NTC thermistors are used for temperature measurement and control.
 

Integration: The NTC thermistor is integrated into the polyimide heater assembly. It's positioned in close proximity to the area being heated so that it can accurately sense the temperature of that area.
 

Temperature Sensing: As the polyimide heater generates heat, the NTC thermistor continuously measures the temperature of the heated surface or environment.
 

Feedback and Control: The NTC thermistor provides real-time temperature data to a control system. This control system can adjust the power supplied to the polyimide heater based on the measured temperature. If the temperature goes above or below the desired setpoint, the control system can increase or decrease the power to maintain the desired temperature.
 

Regulation: The integration of the NTC thermistor allows the system to achieve precise temperature regulation. It prevents overheating by reducing power when the temperature is too high and increases power when the temperature is too low.

Polyimide heaters with NTC thermistors are used in applications where maintaining a specific temperature is critical. This setup provides feedback and control, enabling the heater to operate within a narrow temperature range and avoid overheating or inadequate heating. Such systems are commonly used in devices like heated blankets, incubators, temperature-controlled containers, and various industrial processes where consistent and precise temperature control is necessary.
