Difference between temperature and humidity recorder and temperature and humidity transmitter

Temperature and humidity recorder and temperature and humidity transmitter are common products in production and manufacturing. They have similar functions and can measure temperature and humidity in the environment, but their functions and application scenarios are somewhat different. So, when we need to measure the temperature and humidity of the surrounding environment, how should we distinguish between the two, so as to select the equipment suitable for ourselves?
Firstly, the temperature and humidity recorder is introduced.
Distinguish in detection principle and function: the temperature and humidity recorder is one of the temperature and humidity meters in the temperature and humidity measuring instruments. It relies on the function of measuring temperature and humidity by the built-in temperature and humidity sensor or connecting the external temperature and humidity sensor. The recorder can be used alone or offline, and can also output a variety of signals, such as RS485 signal and analog signal, in the same way as the temperature and humidity transmitter. Now with the development of time, the temperature and humidity recorder not only has the function of reading and recording, but also has the function of directly exporting, downloading and printing data on the device, which is convenient to carry around.
Temperature and humidity recorders are generally used in cold chain logistics transportation or special goods storage. In cold chain logistics transportation, temperature and humidity are very important to food. In order to prove that goods meet the transportation and storage conditions during long-distance transportation or sea transportation, people will place temperature and humidity recorders in the cargo holds to record temperature and humidity data in different time periods. This not only ensures the safety of the food in the transportation process, but also facilitates the tracing of later events. In case of any problem with the food, it can also help the transportation personnel get rid of the suspicion of accidents in the transportation process.
There will be strict transportation and storage requirements for important special items. There will be a special incubator for transportation and storage. The incubator is equipped with a temperature and humidity recorder to ensure that special products (such as chemical reagents) will not deteriorate or reduce their effectiveness due to environmental factors during transportation and storage, and ensure their final quality.
Secondly, the temperature and humidity transmitter is introduced.
In terms of detection principle and function, the temperature and humidity transmitter mainly uses the temperature and humidity integrated probe as the temperature measuring element. After the temperature and humidity signals in the environment are collected and processed, they are converted into current signals or voltage signals that have a linear relationship with temperature and humidity for output. They can also be output through RS485 and other interfaces through the main control chip.
The temperature and humidity transmitter itself has no function of recording and exporting data, only the function of collecting and outputting data. There are many kinds of temperature and humidity transmitters, including real-time reading with display screen and external display screen without display screen.
Temperature and humidity transmitters are generally used in smart greenhouses or warehouses where real-time monitoring is required. In the smart greenhouse, the greenhouse administrator needs to know whether the temperature and humidity in the greenhouse meet the standard in real time. When the temperature and humidity exceed the standard, it is convenient to control the temperature and humidity of the surrounding environment in time, so as to ensure that the plants in the greenhouse are always in a normal temperature and humidity environment.
Similarly, in meteorological monitoring, temperature and humidity transmitters can measure and forecast weather changes, which is of great significance to industrial and agricultural production and scientific experiments. Therefore, in the field of climate monitoring, temperature and humidity transmitters are also indispensable measuring equipment.
In warehouse storage, different articles have a certain degree of adaptability to the environment, such as textiles, paper products, wood products, etc. if the temperature is too high or too low, the articles will lose their original performance and reduce their service life.
Nowadays, the gap between temperature and humidity transmitter and temperature and humidity recorder is gradually narrowing, and the boundary is not clear as before. Although the temperature and humidity transmitter itself does not have the storage function, it can view real-time data on the monitoring platform through the output signal, filter historical data, export, analyze, print, and generate daily and monthly reports for our convenience. We can also set the safety threshold of the upper and lower limits of temperature and humidity for the equipment to realize automatic alarm. In addition, it can be linked with other temperature control equipment to automatically adjust the ambient temperature and humidity.
In fact, whether it is a temperature and humidity recorder or a temperature and humidity transmitter, its core function is to measure temperature and humidity, but the way of information transmission is different. Nowadays, the development of any industry can not be separated from the air. Therefore, the importance of temperature and humidity monitoring has also been reflected year by year.
