Selection of Ultrasonic Anemometer and Wind Vane Sensor

The selection of Ultrasonic Wind Speed Direction Sensor should take various factors into comprehensive consideration.

Firstly, measurement accuracy is crucial. In scenarios such as meteorological monitoring and scientific research where high data accuracy is required, a high-precision sensor is indispensable. Check the product's technical parameters, including the measurement range and accuracy of wind speed and direction. For a high-quality sensor, the accuracy of wind speed measurement can reach ±0.1m/s, and the accuracy of wind direction can reach ±1° or even higher.

The working environment also matters a great deal. In terms of temperature, if the sensor is to be used in high or low temperature environments, it should be able to adapt to extreme temperatures. Some specially designed sensors can work normally in a temperature range from -40°C to 60°C or even wider. The waterproof and dustproof performance is extremely important for sensors used outdoors for a long time. Those with an IP65 or higher rating can better resist the erosion of rain and dust. If there is electromagnetic interference in the using environment, a sensor with strong anti-interference ability should be selected.

Attention should be paid to the signal output and communication methods. Signal output types include analog signals (such as 4 - 20mA, 0 - 5V, etc.) and digital signals (such as RS485, RS232, Ethernet, etc.). Sensors with digital signal output have high accuracy and stability, which are convenient for data transmission and processing, and are suitable for connecting to data acquisition systems and computers. Those with analog signal output are applicable to occasions where the accuracy requirement is not high. Meanwhile, it should be ensured that the sensor supports the communication protocol of the using system, such as Modbus, CAN, etc.

The response speed is of great significance in specific scenarios. For example, in wind farms and airports, there is a high requirement for monitoring the changes in wind speed and direction. A sensor with a fast response speed can monitor the changes in a timely and accurate manner, providing a basis for control and decision-making.

The brand and after-sales service should not be overlooked either. Choosing a sensor from a well-known brand can ensure better quality and performance. The brand reputation can be understood through product reviews, user feedback, and industry word-of-mouth. Good after-sales service can guarantee the normal use of the sensor. It is necessary to know about the after-sales response speed, maintenance cycle, and technical support, etc.

For example, the FT-wqx2 type Ultrasonic Wind Speed Direction Sensor of Fengtu, its hidden ultrasonic probes on the top cover can avoid the accumulation of rain and snow and the obstruction of natural wind. It adopts ultrasonic sensing technology to measure in real time without a starting wind speed. The output signal is equipped with an RS485 communication interface (Modbus protocol) as standard and other interfaces can be optionally configured. It is maintenance-free and does not require on-site calibration, with high stability and reliability, suitable for various fields. It has a good reputation and inquiries are welcomed.
