50KΩ 3950K Electric Kettle NTC Temperature Sensor
Product Description:
The 50KΩ 3950K Electric Kettle NTC Temperature Sensor is a crucial component found in electric kettles, designed to accurately measure and monitor the temperature of the water during the boiling process. NTC stands for Negative Temperature Coefficient, indicating that the sensor's resistance decreases as the temperature increases.
The sensor's name, "50KΩ 3950K," provides essential information about its characteristics. The "50KΩ" refers to the nominal resistance of the NTC thermistor at a specific reference temperature (often 25°C). In this case, the resistance is 50,000 ohms (Ω) at the reference temperature. However, it's important to note that the actual resistance at other temperatures will deviate from this value, following the NTC's characteristic curve.
The "3950K" denotes the Beta (β) value of the thermistor. The Beta value is a crucial parameter for converting the sensor's resistance into an accurate temperature reading. It represents the rate of change of resistance concerning temperature. With a Beta value of 3950K, the NTC temperature sensor can effectively measure a broad range of temperatures with a high level of precision.
In an electric kettle, the NTC temperature sensor is strategically positioned either within the kettle's heating element or in close proximity to the water being boiled. As the water temperature rises during the boiling process, the resistance of the NTC thermistor decreases accordingly. By measuring this resistance, the kettle's control circuitry can accurately determine the water's temperature.
The NTC temperature sensor plays a vital role in ensuring the electric kettle's optimal functionality. It enables the kettle to maintain precise temperature control during the heating process, preventing the water from reaching excessively high temperatures and boiling over. Additionally, the sensor contributes to safety features like automatic shut-off when the water reaches the desired boiling point, safeguarding against potential hazards and conserving energy.
Overall, the 50KΩ 3950K Electric Kettle NTC Temperature Sensor is a reliable and essential component in electric kettles, providing accurate temperature measurements that enhance the efficiency, safety, and performance of these popular household appliances.
