The application of NTC thermistor in the cold chain temperature recorder.Radar Microwave Induction Sensor Switch Processing

　　The temperature recorder generally has the following basic functions:

　　Measurement: Built -in temperature sensor or connectable external temperature sensor measure temperature;

　　Record storage: automatic record and storage measurement temperature value;

　　Data transmission: transmit or download the saved measurement data through some ways (such as RS232, RS485, USB interface, etc.) to the computer;

　　Programming: such as setting sampling rate, data transmission method and interval, selecting temperature sensor type, alarm settings, etc.;

　　Analysis: Make necessary analysis of temperature data through the software that comes with its own

　　The temperature recorder has the characteristics of small volume, simple operation, and reliable performance. The temperature sensor selected by the temperature recorder must be high precision, the accuracy is usually ± 0.5 ° C, and the long life is required, because in the cold chain transportation, it is usually transported freezing and refrigerated food or medicine on long -distance or ocean.

　　Core of cold chain box: cold chain temperature recorder

　　During the cold chain transportation process, the temperature recorder dedicated to the cold chain box can be used to monitor the temperature changes of the cold chain box in real time. At least 3-5 cold chain temperature recorders need to be configured in the entire cold chain transportation car, and measure the temperature of the carriage every 5 minutes to ensure the safety of the entire cold chain transportation link.

　　The core temperature measurement component of the cold chain transport box is NTC thermistor. It uses the resistance value of the thermistor to change with the characteristics of temperature changes to achieve temperature monitoring of the surrounding environment, and then the data transmission records are used in the temperature recorder to achieve record storage, programming, and analysis.
