CG-23 ultrasonic wind speed wind orientation sensor (wind speed wind direction instrument) -Base wind
Yifeng ultrasonic wind speed wind direction sensor is a wind speed wind direction measurement instrument developed based on the ultrasonic principle. It uses the sending of the receiving end to calculate the wind speed and direction of the time or frequency (Doppler transformation) of the receiving end. This sensor can measure the instantaneous value of wind speed, the wind direction, and support the current, voltage signal output, and RS485, NB-IoT, LORA, GPRS and Ethernet.
The whole machine shell is made of ABS, which has the characteristics of light weight, no mobile components, and solid practicality, and does not need to maintain and calibrate on -site. It can output wind speed and wind direction at the same time. It can be connected to the acquisition device that has RS485 or an analog output in compliance with the computer, data collector or other.

⊙ Working principle
Ultrasonic wind metering is an application of ultrasonic detection technology in the gas medium. It uses ultrasonic to spread the speed of air flow (wind) in the air by ultrasonic waves to measure the wind speed. Compared with the conventional wind cup or rotor -type wind speed instrument, this measurement method is characterized by the entire wind measurement system without mechanical rotation components, which is an inertial measurement. Therefore, it can accurately measure the high -frequency component of the gusts in the natural wind.
Ultrasonic wind speed winding sensors use four ultrasonic probes to send and receive ultrasonic in the two -dimensional plane, and measure the wind speed and wind direction through the time difference between the transmission of ultrasonic spreads in the air.
