The application of data logger in various fields

[2012-02-18]

Temperature and humidity measuring is the modern measuring newly developed a field, especially moisture measurement is ceaselessly. Experienced length method, dry and wet law until today's electric measurement process, make humidity measurement technology mature. Today, because we are no longer satisfied with humiture survey, especially some places of the real-time monitoring records its whole directly requirements changes, and on the basis of the data logger changes recognized the safety of transportation, has led to new temperature and humidity measuring instrument - the birth of data logger.
Data logger is measured in accordance with the temperature and humidity parameters and the expected time interval will be stored in internal memory, in complete record function when the linked to the PC, using adaptive software will put forward the data stored on the numerical analysis instruments, time. Using this instrument can determine the storage process, the experimental process related process without any compromise product safety incident.
1.    Food storage: because food storage and transportation time isn't a short-term problems, but food preservation the relative balance humidity and ensure food safety of an important index, relative balance humidity directly affect the growth of colonies. Moisture absorption material balance relative humidity played a decisive role. Balance relative humidity is defined as material and moisture air does not undertake exchange circumstances, the surrounding air humidity value gain. This definition is very clear, in order to successfully storage and maintain these products, environmental climate control and packing must be carefully indicated. At the same time, many food stored in too dry circumstance, its mouthfeel can have some bad. In view of this situation, the data logger is useful for food storage.
2.    Museum of cultural relics, file management: archives of paper in temperature and humidity conditions may be more suitable deposit some time, but once temperature and humidity conditions damaged paper will become fragile, important material will accordingly alls gone on record to archives, temperature and humidity is necessary, can prevent malignant accidents. Use of data logger will make temperature and humidity records of work, also will save simplifies the cultural relics preservation of cost, make this work to be able to scientific, not by excessive human factors of interference. At the same time due to the tiny devices, ensure the minimum damage artwork, under the precondition of cultural relics, including its color, shape not damaged destroyed.
3.    Building material experiment: in building materials, especially concrete in drying process, we should pay attention to its drying trend, which is one of the index evaluation products for the building construction, but also provides the reliable data. This application data logger can record data and provide building materials research square, will provide useful help for construction. Especially in military architecture, time is life, an accurate grasp of the concrete drying time first hair caused by enemy, to effectively will provide effective strength to the battlefield provides guarantee.
4.    Agriculture and animal husbandry applications: agriculture and animal husbandry production, especially some economic crop production, in its seedling stage to detailed record temperature and humidity value. While in agricultural applications, due to bad environment - fertilizer, excrement and make the acid and alkaline environment make humidity product drift, so other environment beyond the requirement wet sensitive capacitance drift, lesser, the machine calibration is convenient.
