Effect of temperature and humidity recorder sensor on increasing breathable film

Another function of the commonly used waterproof and breathable interlayer film is to prevent the sudden rise of temperature and humidity data due to the operation of opening and closing the door when the temperature and humidity recorder is used in a cool cabinet or refrigerator, resulting in sudden alarm. It plays the role that temperature and humidity data measurement is the central data. At present, temperature and humidity recorders are used in cold storage, cool cabinets, or food, cold storage and preservation in many occasions. Generally, the humidity in this situation is very high, and it will condense into water, which has a great influence on the sensor. After long-term use, the temperature and humidity sensor will fluctuate greatly, and sometimes even 100% will appear. In view of this problem, our current temperature and humidity recorder adopts waterproof and breathable film to apply to the temperature and humidity sensor.

Different control schemes of temperature and humidity recorder in warehouse pharmacy

The following requirements shall be met:

The installed quantity of measuring terminals in warehouses for storing refrigerated and frozen drugs shall meet the above requirements of this article, and the installed quantity shall be calculated per 100 square meters.

Each independent refrigerated and frozen drug transport vehicle or carriage shall be equipped with no less than 2 measuring terminals. If the carriage volume exceeds 20 cubic meters, at least one measuring point terminal will be added for each additional 20 cubic meters, and less than 20 cubic meters will be calculated as 20 cubic meters.

Each refrigerator or incubator shall be equipped with at least one measuring point terminal. (1) Each independent drug warehouse or warehouse shall be equipped with at least 2 measuring point terminals, which shall be evenly distributed.

(two) the plane warehouse area is less than 300 square meters, and at least 2 measuring terminals are installed; More than 300 square meters, each additional 300 square meters at least one measuring point terminal, less than 300 square meters by 300 square meters.

The location where the measuring terminal of the flat warehouse is installed shall not be less than 2/3 of the height of the drug shelf or drug stacking.

(3) If the shelf height of an elevated warehouse or a fully automatic three-dimensional warehouse is between 4.5 meters and 8 meters, at least 4 measuring terminals shall be installed every 300 square meters, and at least 2 measuring terminals shall be added every 300 square meters, which shall be evenly distributed on the upper and lower positions of the shelf; If the height of the shelf is more than 8 meters, at least 6 measuring terminals shall be installed every 300 square meters, and at least 3 measuring terminals shall be added every 300 square meters, which shall be evenly distributed in the upper, middle and lower positions of the shelf; Less than 300 square meters is calculated as 300 square meters.

The installation position of the upper measuring point terminal of the overhead warehouse or the fully automatic three-dimensional warehouse shall not be lower than the highest position for storing drugs on the top shelf.
