For coffee lovers, a perfect cup of coffee is made of carefully selecting high-quality coffee beans, mastering roasting techniques, and controlling the water temperature. In coffee machines, NTC temperature sensors play a key role in ensuring precise control of coffee water temperature, allowing us to enjoy a wonderful coffee experience.
How does an NTC coffee machine work?
The NTC temperature sensor of coffee machines is a negative temperature coefficient thermistor its resistance decreases as the water temperature increases. Such sensors are installed at strategic locations in waterways to measure water temperature. As water flows, the sensor detects the changes in water temperature and converts them into electrical signals to the coffee machine control system.
Function of NTC temperature sensor in coffee machine.
1.Precise temperature control: The taste and flavor of coffee are greatly affected by water temperature. If the water temperature is too high, the coffee may be over-extracted, resulting in a bitter taste; on the contrary, if the water temperature is too low, the aroma and taste of the coffee cannot be fully released. The NTC temperature sensor is used to monitor the water temperature in real time, and the power of the heating element is adjusted through the feedback control system to ensure that the water temperature is stable within the ideal range.
2.Safety protection: High-temperature water is potentially dangerous to the human body. The NTC temperature sensor monitors the water temperature in the coffee machine. When the water temperature exceeds the safe range, the sensor will send a signal to the control system and trigger a safety protection mechanism, such as automatically stopping heating or sounding an alarm, to protect user safety.
3.User experience improvement: NTC temperature sensor application allows the coffee machine to perform personalized temperature adjustment according to user preferences. Different coffee types and taste preferences may require different water temperatures. The presence of sensors allows users to adjust the coffee heat according to their own preferences, providing a coffee experience that is more in line with personal tastes.
NTC temperature sensors play an important role in coffee machines. Through precise temperature control, they ensure the taste and flavor of coffee, and also provide safety protection for users.
