technical field

The invention relates to the field of automatic control of humidity and temperature, and more specifically relates to a calibration device for automatic control of humidity, temperature and flow rate.

Background technique

Simply put, humidity is the content of water vapor in the gas. This is the absolute humidity. Generally speaking, it is difficult to measure and understand. For example, when you see that the humidity in the air is 10g/m3 or When it is 17.1g/kg, it is impossible to effectively grasp the meaning. Humidity is a very important parameter, which not only affects the comfort in our daily life, but also affects many links in the production process. Improper humidity control will affect the physical properties, chemical shape and biological characteristics of the object to be investigated Significant changes will occur.

For the laboratory, the requirements on temperature and air humidity are relatively strict, but after the vaporizer works for a long time, certain failures may occur, resulting in the water introduced into the vaporizer not being gasified in time and sprayed into the air , leading to poor control of air humidity and affecting changes in experimental data. In "A Humidity, Temperature, and Flow Velocity Automatic Control Calibration Device" disclosed in Chinese patent CN202110084655.1, a fault is triggered by a floating ball to trigger a travel switch, but In this way, since the resistance force generated by the float to the travel switch is unstable, it may be difficult to trigger it, making it difficult for the staff to adjust the control of the air humidity in time.
