With the popularization of coffee culture and the acceleration of the pace of life, portable coffee makers have gradually become the new favorite of coffee lovers because of their convenience and efficiency. In order to ensure a rich coffee taste and a safe use process, the portable coffee maker is equipped with NTC thermistors for water temperature monitoring and control, so that users can get a better brewing experience.

Compared with traditional desktop coffee maker, the biggest advantage of portable coffee maker is that it is easy to carry and small in size. Moreover, traditional desktop coffee maker needs to be connected to a power outlet to work, while portable coffee maker is powered by built-in battery, combined with NTC thermistor, which can quickly and accurately control the water temperature in any location, provide different levels of extracted temperature to meet the needs of users for various coffee flavors. Thermistors are generally installed in the monitoring module of the portable coffee maker for real-time water temperature monitoring, and installed in the control module for real-time water temperature control, helping the microprocessor of the coffee maker to adjust the heating power in time to keep the water temperature stable. Specifically:

First, temperature control: After the user starts the portable coffee maker and selects the extracted temperature, the microprocessor will transmit the information to the heating module, then the NTC thermistor will start to monitor the water temperature; When the temperature reaches the specified temperature, the NTC will feed back the temperature signal to the microprocessor, then the microprocessor will send instructions to the control module, the coffee maker will stop heating.

Second, temperature monitoring: The microprocessor will preset the maximum temperature threshold, when the working water temperature of the portable coffee maker rises abnormally and the temperature value is higher than the preset temperature threshold, the NTC thermistor will respond quickly and trigger the protection mechanism, and at the same time feeds back the information to the microprocessor; The microprocessor immediately sends a command to cut off the power supply to the heating module.

In summary, NTC thermistor can not only help the portable coffee maker to make mellow coffee, but also ensure the safety of users. In order to ensure that the water temperature is precisely maintained in the ideal brewing interval, and to improve the safety of portable coffee machines, the technical requirements for NTC thermistor are also very strict in portable coffee maker. EXSENSE Electronics Technology Co., Ltd. recommends IT series miniature insulated lead NTC thermistor. Its high accuracy can effectively improve the accuracy of the water temperature control of the coffee maker, so that the coffee extraction tastes better. In addition, the IT series NTC is highly sensitive to temperature and provides excellent assistance to the coffee maker in monitoring the water temperature. The head size of the miniature insulated lead NTC thermistor is small and the leads can be bent, which can be highly coordinated with the development of portable coffee maker in the direction of miniaturization.
