Defrost temperature sensor for car air conditioner and refrigerator

Refrigerator Defrost Sensor monitors the refrigerator temperature and signals the main control board to begin the defrost cycle. Temperature Sensor for Defrost Termination 2M · Sensor Type: NTC 10K, 10000Ω @ 25°C · Range: -40÷120°C · Accuracy: ±0.3°C @ 25°C · Sheath: Ø 6 x30，Ø 5 x 200. Refrigerator Defrost Sensor with Thermal Fuse & thermostat switch Sensing temperature function.

Function and installation location of refrigerator defrost sensor:
Refrigerator defrost sensor is a sensor that can detect the degree of frosting inside the refrigerator and automatically defrost when it reaches a certain level. The principle is to detect the degree of frosting inside the refrigerator and transmit the signal to the controller to achieve the function of automatic defrosting. This sensor is usually installed in the freezer of the refrigerator.

Function and installation location of temperature sensor
Temperature sensor is a sensor used to measure the temperature of an object. In a refrigerator, the temperature sensor is generally used to measure the temperature inside the refrigerator and transmit the temperature signal to the controller. The feedback signal of the controller can be used to control the temperature inside the refrigerator. This sensor is usually installed in the cooling room or freezer inside the refrigerator.

Difference between refrigerator defrost sensor and temperature sensor
From the perspective of function, the refrigerator defrost sensor is mainly used to detect the degree of frosting inside the refrigerator and automatically defrost. The temperature sensor is mainly used to measure the temperature inside the refrigerator to achieve the control of the refrigerator temperature. The physical quantities measured by the two are different.
From the perspective of installation location, the refrigerator defrost sensor is mainly installed in the freezer, while the temperature sensor is mainly installed in the cooling room or freezer. Since the two sensors are installed in different locations, the physical quantities they measure are also different.
In summary, refrigerator defrost sensors and temperature sensors are two different sensors with different uses, different measured physical quantities, and different installation locations. When purchasing, installing, and maintaining them, you need to make reasonable choices and use them according to actual needs.
