In coffee brewing, extraction water temperature is considered a key variable in determining flavor levels. When the water temperature of the coffee machine is stable in the extraction range, the fruit acids, sugar compounds, etc. in the coffee beans can achieve an ideal dissolution balance. To achieve this precise temperature control, the coffee machine uses EXSENSE NTC temperature sensors as the temperature measurement components to ensure that it can bring users with better coffee taste and ensure the safety of the coffee brewing process at the same time.
During the operation of the coffee machine, the real-time temperature monitoring of its water system and thermal components of the NTC temperature sensors can provide effective temperature feedback to the MCU, so that the coffee machine can maintain excellent working condition. Therefore, the installation positions of the EXSENSE NTC temperature sensors directly affect the accuracy of the temperature measurement:
1. Heating coil
The NTC temperature sensor is attached to the heating coil to monitor the surface temperature of it. The NTC is installed at this location to prevent the heating coil from causing abnormal temperature due to local overload or temperature control failure, which can cause the coffee to taste bad and even damage the equipment.
2. Heater water outlet
For instant coffee machines, temperature monitoring of the spout is critical as the water flow needs to be heated to a set temperature instantaneously in the runner. The EXSENSE temperature sensor at this location provides real-time feedback on the actual temperature of the outflow hot water, and the MCU can dynamically adjust the heating power to ensure that the water temperature injected into the coffee machine extraction chamber can still be maintained at the preset target temperature value even when the water flow rate fluctuates, preventing over/too low temperature problems caused by thermal inertia of the heater or water flow disturbances.
No matter where the EXSENSE NTC temperature sensors are installed, which relies on their excellent electrical performance to complement the coffee machine temperature monitoring process:
First, high accuracy, ensure coffee extraction rate
Suitable water temperature is the basis for ensuring coffee flavor, and the EXSENSE temperature sensor has a high accuracy of 1% is a key component to assist the coffee machine in reproducing the aromatic coffee. With its high-accuracy characteristic, the NTC temperature sensor can control the water temperature within a smaller error range, providing a strong guarantee for coffee extraction and meeting users' pursuit of high-quality coffee.
Second, fast response speed, respond to temperature changes in time
When the coffee machine heats up or stops heating, the water temperature changes instantaneously, and the NTC temperature sensor can sense this change in a short time and quickly transmit the signal to the MCU. The MCU then adjusts the heating power to achieve rapid temperature heating, cooling, or constant temperature control, ensuring that the coffee making process is efficient and stable.
As an important part of the precise temperature monitoring of the coffee machine, the EXSENSE NTC temperature sensor is not only the "collector" of temperature data, but also the "guardian" of the smooth and safe operation of the coffee machine. In terms of user experience, the EXSENSE temperature sensor helps the coffee machine achieve personalized temperature adjustment, making the coffee brewing flavor richer, which greatly improves the user experience. In terms of equipment safety, the EXSENSE coffee machine NTC temperature sensor monitors and feeds back on abnormal temperatures, which avoids damage to the equipment due to abnormal temperatures, extends the service life of the coffee machine and reduces maintenance costs.
