A80F-2D1 Ultrasonic Anemometer
¨€ PREFACE
Forereach A80F-2D1 anemometer is an instrument using the difference of the ultrasonic flight time in the air to measure wind speed and wind direction. Its internal heating device can make sure the equipment work well in the winter, and various output mode options can meet different industry standards, which makes the operations more simple and convenient.
Compared with the traditional mechanical anemometers, the ultrasonic anemometers have much advantages as follows£º
¡ñNo moving parts, less wear£»
¡ñLow maintenance, long service life£»
¡ñFast response£»
Compared with the current foreign and domestic products, the ultrasonic detection of A80F-2D1 uses all-digital signal processing.
Although traditional analog signal detection methods have faster response, lower cost than digital signal methods, these ways demand the stability of the device and the external environment high, which are difficult to achieve high performance detection. However, The wind speed and direction measuring demand low to the response rate of the instrument, but high to the environment range. So A80F-2D1 choose all-digital signal processing, which made it more accurate and intelligent.
The advantages£º
¡ñUsing sound wave phase compensation technique, have higher accuracy£»
¡ñUsing random error recognition technology, it make sure low disperse errors even if in strong wind, that makes the output more stable£»
¡ñUsing weather compensation for rain and fog technique, make the instrument have a strong ability to adapt to various weather£»
¡ñUsing digital filter technology, make the instrument have stronger resistance to electromagnetic interference£»

¨€ INTRODUCTION
A80F-2D1 is an ultrasonic anemometer which have all digital signal detection, high accuracy, It can achieve real-time measurement of wind speed, wind direction and acoustic temperature.
Equipment is connected by an 8-pin waterproof plug.
Measurement results has several output modes :
- RS485/RS422 output
¡ð NMEA0813 protocol;
¡ð Modbus-RTL protocol;
- analogue output
¡ð 4-20mA current output for wind speed and wind direction;
¡ð 2-500Hz pulse output for wind speed, 4-20mA current output for wind direction;
1 Wind speed and direction
Ultrasonic anemometer send and receive ultrasonic using four ultrasonic sensors in the two-dimensional plane. It measure wind speed and wind direction using ultrasonic flight time difference in the air.
2 Acoustic temperature
Ultrasonic anemometer can calculate the sound speed in the air by ultrasonic flight time, and thus calculate the temperature through the physical relationship between temperature and sound speed.
