Metal five-element weather sensor

1. Overview of metal five-element weather sensor products

The metal five-element weather sensor is also called five-element sensor and five-element weather monitor. The metal five-element weather sensor is a compact and high-precision weather sensor, including five elements of wind speed, wind direction, temperature, humidity, and atmospheric pressure. . The application is convenient and accurate, and it can be used flexibly in many fields. It is widely used in urban environmental monitoring, wind power generation, meteorological monitoring, bridges and tunnels, navigation ships, aviation airports, various fan manufacturing industries, industries that require exhaust systems, etc. The working principle of the ultrasonic sensor is to use the ultrasonic time difference method to realize the measurement of wind speed. Because it overcomes the inherent defects of the mechanical anemometer, it can work normally for a long time around the clock, and is more and more widely used. It will be a powerful replacement for mechanical anemometers.

2. The structure and working principle of the metal five-element meteorological sensor system

The working principle of ultrasonic is to use ultrasonic time difference method to realize the measurement of wind speed. The velocity of sound in the air is superimposed on the velocity of the airflow in the wind direction. If the ultrasonic wave travels in the same direction as the wind, its speed will increase; conversely, if the ultrasonic wave travels in the opposite direction to the wind, its speed will slow down. Therefore, under fixed detection conditions, the speed of ultrasonic waves propagating in the air can correspond to the wind speed function. Accurate wind speed and wind direction can be obtained through calculation. Since the speed of a sound wave is greatly affected by temperature as it travels through the air; an anemometer detects two opposite directions on two channels, so the effect of temperature on the speed of sound waves is negligible. Users can choose the wind speed unit, output frequency and output format according to their needs. Optional heating (recommended for icy environments) or analog output is also available upon request.
