Application Information
This NTC thermistor serves as a critical temperature control component in induction cookers. When temperature reaches predetermined values, the heating device automatically disconnects for safety. The sensor connects to the MCU interface on the induction heating control board, enabling precise level detection and protective functions.
Testing Procedure
To verify functionality, remove the sensor and measure resistance changes using a multimeter while applying heat. As temperature increases, resistance should decrease (negative temperature coefficient characteristic). At room temperature, resistance should measure approximately 100kΩ.
