PREFACEForereach 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:●No moving parts, less wear;●Low maintenance, long service life;●Fast 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:●Using sound wave phase compensation technique, have higher accuracy;●Using random error recognition technology, it make sure low disperse errors even if in strong wind, that makes the output more stable;●Using weather compensation for rain and fog technique, make the instrument have a strong ability to adapt to various weather;●Using digital filter technology, make the instrument have stronger resistance to electromagnetic interference;TECHNICAL PARAMETER1 Power supplyWork power supply:24V±20% / 0.3AHeating power supply:24V±20% / 10A (Cancelled)2 Wind SpeedMeasure range:0—60m/sAccuracy:<=10m/s :±0.2m/s>10m/s :<±2% (FS)Resolution:NMEA protocol: 0.1 m/sOther protocol 0.01m/s3 Wind directionMeasure range:0—360°Accuracy:±1°Resolution:0.1°4 TemperatureMeasure range:-40℃—70℃Accuracy:±2℃Resolution:0.1℃5 Output modeAnalogue output:4—20mA,0—20mADigital output:RS422,RS485Communication protocol:NMEA0183·WIMWVSample rate:1Hz---10Hz6 Operation environmentStorage temperature:-50℃—80℃Work temperature:-40℃—60℃Protection Type:IP66DIMENSION DRAWING
