High Sensitivity Embedded Temperature Sensor Resistor For GF21388 Commercial Coffee Machine

High Sensitivity Embedded Temperature Sensor Resistor For GF21388 Commercial Coffee Machine

Description Of The Temperature Sensor Resistor

There are three main types of coffee machines in the market currently. Drip coffee machine, siphon coffee machine, pressure type coffee machine.
Most of the three types of coffee machines have a limited temperature range, which automatically disconnects the switch, and the amount of coffee is either fixed, and not required people to hold the switch.
This requires a coffee machine that can automatically control the temperature. Therefore, the temperature sensor must be installed on the coffee machine.

The temperature sensor of the coffee machine is changed by the resistance of the NTC thermistor with the ambient temperature or the heat from the current.

That is under certain measurement power, the resistance value decreases rapidly with the temperature rise.

This characteristic is used to determine the corresponding temperature by measuring the resistance of NTC thermistor to achieve the purpose of detecting and controlling temperature. The flow chart of temperature control is as picture

Feature Of The Temperature Sensor Resistor

Material of metal case is the same as that of detected object for more accurate temperature detection, and the shortest response time is around 1 second. Sensor contacts beverage directly to detect temperature, and food grade metal is used for user’s heatlh.

Application Of The Temperature Sensor Resistor

The sensor is mostly adopted by coffee maker, soy milk maker, electric water heater, milk warmer, etc. In addition, the sensor is generally installed in either beverage warmer or hot water boiler, and it can be put into beverage for direct temperature detection.
