INTRODUCTIONA60F-2D2 is an ultrasonic anemometer which have all digital signal detection, high accuracy, automatically heating ability against snow and ice. 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● NMEA0813 protocol;● Modbus-RTL protocol;Analogue output● 4-20mA current output for wind speed and wind direction;● 2-500Hz pulse output for wind speed, 4-20mA current output for wind direction;1 Wind speed and directionUltrasonic 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 temperatureUltrasonic 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.3 Automatic HeatingTo prevent ultrasonic sensors frozen by cold air, so as to affect the result and cause serious damage to the instruments, an automatically heating device is installed in the anemometer to ensure the instrument work well in serious cold environment.TECHNICAL PARAMETER1 Power supplyWork power supply: 24V±20% / 0.2AHeating power supply: 24V±20% / 3A2 Wind SpeedMeasure range: 0~60m/sAccuracy: 10m/s: <±1.5% (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°C ~60°CAccuracy: ±2°CResolution: 0.1°C5 Output modeAnalogue output: 4~20mA, 0~20mADigital output: RS422, RS485Communication protocol: NMEA0183·WIMWVSample rate: 1Hz~10Hz6 Operation environmentStorage temperature: -50°C ~80°CWork temperature: -40°C ~60°CProtection Type: IP66DIMENSION DRAWING
