100K Electric Kettle NTC Temperature Probe Surface Mount

100K Electric Kettle NTC Temperature Probe

In an electric kettle with a 100K NTC (Negative Temperature Coefficient) thermistor as the temperature probe, the "100K" refers to the nominal resistance of the thermistor at a standard temperature, often 25 degrees Celsius.

Nominal Resistance: The 100K NTC thermistor has a nominal resistance of 100,000 ohms (100 kilohms) at a specific reference temperature, usually 25°C. This value is crucial for calibration and temperature measurement.

Placement: The NTC temperature probe is positioned inside the electric kettle, typically in contact with the water. It may be integrated into the heating element or placed in close proximity to where the water is being heated.

Temperature Sensing: As the water temperature changes, the resistance of the 100K NTC thermistor also changes according to its negative temperature coefficient. The thermistor's resistance decreases as the temperature increases.

Wiring and Circuitry: The NTC thermistor is connected to the kettle's control circuitry, forming part of a voltage divider circuit. The change in resistance of the thermistor affects the voltage across the circuit, and this voltage variation is measured by the control system.

Control System: The electric kettle's control system uses the temperature information gathered from the NTC thermistor to regulate the heating element. It can adjust the heating power or turn off the heating element when the water reaches the desired temperature.

Boil-Dry Protection: The NTC temperature probe is instrumental in boil-dry protection. By monitoring the temperature and detecting a lack of water, the control system can initiate safety measures, such as automatically turning off the heating element to prevent damage or hazards.

Calibration: Calibration ensures the accuracy of temperature readings. Manufacturers calibrate the NTC thermistor by comparing its resistance-temperature characteristics to known standards. This calibration allows the electric kettle to provide precise temperature control.

Safety Features: The NTC temperature probe contributes to the overall safety of the electric kettle. Beyond boil-dry protection, it helps prevent overheating and ensures that the kettle operates within safe temperature limits.
