1、No start-up wind speed limit, zero wind speed operation, no angle limit, 360 degree all-round, and wind speed and wind direction data can be obtained at the same time. 2、With the technology of acoustic phase compensation, it has high precision and quick response speed. 3、By using random error identification technology, the low discrete error of measurement can be ensured under strong wind, and the output is more stable. 4、Made of high quality material, durable, wear-resistant, light design, portable, easy to install and disassemble. 5、Integrated design, no moving parts, small wear, long service life, no maintenance and field calibration. 6、Easy access to the port, support 4-20MA type, can measure customs, wind direction, temperature, humidity, etc. 1 x Wind Sensor Condition: 100% Brand NewItem Type: Wind SensorMaterial: PlasticWind Speed Measurement Range: 0-60m/SWind Speed Measurement Accuracy: ±2%Wind Direction Measurement Range: 0 - 360 degreeWind Direction Measurement Accuracy: ±3°Response Time: Less Than 5 SecondsBaud Rate: 9600Communication Port: 4-20MAPower Supply: 12VDCWorking Current: 70MAOperating Temperature: -30 - 80 ° COperating Humidity Environment: 0-100% RH (15-95% RH)Weight: Approx. 687g / 24.2ozSize: Approx. 16x14cm / 6.3x 5.5in Installation:Flange installation is adopted, and threaded flange connection makes the pipe fitting at the lower part of the wind direction sensor firmly fixed on the flange plate. Four mounting holes are opened on the circumference of the chassis, which are tightly fixed on the bracket with bolts, so as to keep the whole instrument at the best level, ensure the accuracy of wind direction data, facilitate the use of flange connection, and be able to bear large pressure.Wring: Connection Model Cable Color Instruction  Power  Red  Power Positive  Power  Black  Power Negative  Communication Yellow (Gray) Current Output Positive (Wind Speed)  Communication Blue Current Output Positive (Wind Direction)
