Modern Temperature and Humidity Sensor Technology Used in Spraying Workshop can Improve Quality

There are two main factors in the air environment: humidity and temperature. They are of great significance to people's lives, work, and industrial production, and they have a considerable impact. In the coating industry, it is necessary to strictly control the temperature and humidity in the workshop environment. As a simple temperature and humidity control equipment, spray humidifier equipment is widely used in this industry. For the paint shop, for example, the spray booth needs to strictly control the temperature and humidity due to process requirements. The built-in temperature and humidity sensor in the humidifier can effectively monitor the temperature and humidity in the coating line of the paint shop, thereby ensuring the production quality and improving the production efficiency of the product.

In the spraying workshop, such as the process of painting solid wood furniture in the spray booth, the environmental factors that have a greater impact on the spraying effect are temperature, humidity, and air cleanliness. The temperature is generally controlled at 25±3℃, and the humidity is generally controlled at 65±15%. Too high or low temperature and humidity are not good. If the temperature is too high, the gloss of the paint surface will be poor, and it will appear matt, rough, orange peel, and the paint film will be lighter and whiter. As a simple humidification equipment, the dry spray humidifier has no complicated mechanical mechanism, and the humidification effect is direct and fast.

First, understand the principle of the sprayer. In short, due to the flow of air, the air with high humidity will move to the space with low humidity. Eventually, the humidity in all locations will increase, thereby reducing the number of air particles. When in use, the dry mist humidification system sprays water mist with an average particle size of 8μm. The dense and fine water mist can easily capture the fine dust in the air. The captured fine dust will naturally fall and settle due to its increased mass. The captured fine dust will also absorb moisture in the air, increase in mass, and settle naturally.

As the air humidity increases, the electrostatic voltage between the air dust will also decrease. When the relative humidity of the air in the line reaches 60%, the electrostatic voltage can basically drop to the lowest point. At this time, the air is accumulated by the electrostatic effect. The disintegration of floating dust achieves the maximum effect, forming tiny floating dust that does not produce paint particles.

Temperature and humidity sensor refers to a device or device that can convert temperature and humidity into electrical signals that can be easily measured and processed. In actual production, the grasp and control of temperature and humidity are of great significance to the improvement of production. Therefore, the integrated temperature and humidity sensor came into being. The temperature and humidity sensor on the market generally measures temperature and relative humidity.

In a common humidifier system, a humidity sensor is built-in, and a control valve is activated. The humidity sensor monitors the humidity in the line and feeds it back to the controller. The controller opens the valve according to the humidity in the line, and finally, the humidifier starts to humidify the chamber.

At present, most of the most popular temperature and humidity sensors on the market are digital outputs. Gongcai.com has introduced a digital temperature and humidity sensor-HTU21D from abroad. The built-in temperature sensor can be in the same package as the humidity sensor. Relative humidity) for temperature compensation measurement, and provide a second independent temperature sensor output, allowing users to replace two sensors with one sensor. In addition, this type of temperature and humidity sensor has the advantages of low energy consumption and high accuracy. However, different temperature and humidity sensors are very different in principle and structure. When selecting related products, you can choose a temperature and humidity sensor reasonably according to the specific measurement purpose, measurement object, and measurement environment.
