MH-CSX Ultrasonic Wind Speed and Direction Sensor

1、 Introduction and working principle:

The MH-CSX ultrasonic wind speed and direction sensor, also known as ultrasonic wind speed and direction meter or ultrasonic wind speed and direction meter, can be combined with different acquisition devices to form a multi-channel wind speed and direction monitoring system. Its working principle is to use ultrasonic time difference method to measure wind speed and direction. Due to the superposition of the speed of sound propagation in the air and the airflow velocity in the wind direction. If the propagation direction of ultrasound is the same as the wind direction, its speed will increase; On the contrary, if the propagation direction of ultrasound is opposite to the wind direction, its speed will slow down. So, under fixed detection conditions, the speed of ultrasound propagation in air can correspond to the wind speed function. Accurate wind speed and direction can be obtained through calculation. This sensor has high measurement accuracy, reliable performance, easy portability, no moving parts, and does not require maintenance or on-site calibration. It is a relatively good instrument for measuring wind speed and direction.



2、 Product features:

1. Adopting a stainless steel integrated design, the appearance is exquisite, and the sensing technology measures in real-time. Compared with mechanical wind speed and direction sensors, there is no starting wind speed limit, no angle limit, and data on wind speed and direction can be obtained at the same time.

2. Multiple ultrasonic probes transmit and receive ultrasonic signals in real-time within the measurement space, ensuring efficient and real-time parameter measurement.

3. The MH-CSX ultrasonic wind speed and direction sensor has high measurement accuracy, wide range, good stability, low power consumption, strong resistance to external interference, can work 24/7, is not affected by weather changes, and does not require calibration.

4. Precise craftsmanship, all solid state design, more robust structure, high strength, weather resistance, corrosion resistance, and waterproofing, with a long service life.

5. Professional integrated installation method, compact size, easy to carry and install.

6. It can be powered by matching solar panels and batteries, with remote wireless transmission of measurement information and remote rear detection. It can be widely used in remote areas such as high mountains and islands with harsh environments and unmanned operations.
