Wind affects our life all the time. In modern society, with the development of science and technology, wind speed and direction sensors used to measure the direction and size of the wind have been widely used in meteorological monitoring. At present, there are many cup anemometers on the market. Regarding how to distinguish the quality of wind speed sensors, the following summary is made:
Material
At present, there are two kinds of product materials on the market, one is ordinary ABS plastic material, and the other is polycarbonate material. When choosing an anemometer, we recommend that you choose a polycarbonate material for the following reasons:
Temperature resistance: The polycarbonate material has excellent high and low temperature resistance, no deformation of the material, and stable strength. The ordinary ABS plastic has poor high temperature resistance, it is easy to deform at high temperature, and it is easy to become brittle at low temperature.
Weathering resistance: Polycarbonate material is a thermoplastic engineering plastic with excellent performance, which is resistant to weathering for a long time. Ordinary ABS plastic is easy to change color after long-term use, and is easy to degrade under the action of ultraviolet rays.
Weather resistance: Polycarbonate material has outstanding impact resistance and good dimensional stability. The weather resistance of ordinary ABS plastic is poor, and the impact strength will drop by 50% after half a year outdoors.
Detail
Look at the product quality from the details. After comparison, we found that some products have bearing brim, and many products do not. Even the small bearing brim, its function is still very large. The anemometer generally works outdoors. The outdoor environment is harsh, and it may encounter rain and snow weather at any time. The bearing brim can prevent rain and water, and the protection level is improved, and the working performance is more stable. An anemometer without a bearing brim is prone to water seepage in rainy and snowy weather, causing damage to the circuit board.
The three-cup anemometer is compact and lightweight, easy to carry and assemble. The three-cup design concept can effectively obtain wind speed information. The shell is made of polycarbonate composite material, and a variety of output modes can be selected arbitrarily. The three-cup wind speed sensor adopts the cutting-edge product design, and has two outlet methods: bottom outlet and side outlet, and the bottom outlet has higher rain and snow resistance.
