Weather plays an important role in our daily life and affects all aspects of people’s daily activities. Although it has the uncontrollability of “weather is something that people can be caught off guard against, sometimes it is windy and rainy and sometimes cloudy”, it is also knowable, and we can predict the weather in advance through methods such as weather forecasts.
When we look at the weather forecast, we usually focus on common indicators such as temperature, body sensation, and air quality. In fact, there is an important indicator that is rarely understood by the public – dew point temperature. It often only appears in the official observations and forecasts of the Central Meteorological Observatory, and generally rarely enters the field of view of the general public.
what is dew point temperature
The dew point temperature refers to the temperature at which the air is cooled to saturation under the condition that the water vapor content and air pressure do not change. Because the atmosphere’s ability to carry water vapor is limited, generally the higher the temperature, the more water vapor it can carry. When the amount of water vapor remains unchanged and the temperature drops to a certain level, the water vapor will be saturated, and this critical temperature is the dew point temperature. To put it figuratively, the temperature at which water vapor in the air turns into dew is called the dew point temperature. The higher the dew point temperature and the closer it is to the air temperature, the more humid the air is. Therefore, dew point temperature can be used to indicate humidity. For the human body, if the dew point temperature exceeds 20°C, there will be a sultry feeling. If the dew point temperature exceeds 24°C, the sultry feeling will be stronger. When it reaches 28°C, the life is basically given by the air conditioner.
In the fields of industry, scientific research, etc., the monitoring of dew point temperature is one of the important work contents. Only by doing this step of monitoring work well can follow-up projects and research be better carried out. Today, these fields are expanding, and the demand for dew point temperature and humidity monitoring is also increasing. Although there are many dew point monitoring instruments on the market, most of them can only be used in specific occasions, and although some dew point instruments measure accurately, they are prohibitive in terms of operation difficulty. Therefore, our company has developed a device that provides users with fast and accurate monitoring of dew point temperature and humidity – dew point temperature and humidity sensor. It uses 10~30V wide voltage DC power supply, adopts wall-mounted installation, which is convenient for users to operate. It can be applied to various places that require dew point temperature and humidity monitoring, and can better meet the needs of the rapid development of today’s industrial enterprises.
