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.
