Function: 1. The surface is electroplated and sprayed treatment which is anti-corrosive and anti-invasive, and has no rust phenomenon for a long time. 2. Due to the moisture-resistant and corrosion-resistant aluminum alloy shell, high measuring precision and wide measuring range, it is a special meteorological measuring tool. 3. Innovative design, 360 degree wind speed measurement, low power consumption, stable performance, accurate measurement. 4. The base is stable, which increases the load capacity and anti-interference ability, and ensures measurement accuracy. 5. With high quality aviation cable connectors, it has excellent anti-corrosion and anti-erosion functions. 6. Black shielded cable, waterproof, oil-proof, four-core cable, strong anti-interference ability, stable signal transmission. 7. Small size, light weight, reduce friction, improve sensitivity, ensure measurement accuracy. 8. It is widely used to measure wind direction in greenhouses, environmental protection, weather stations, ships, aquaculture and other places. Specification: Item Type: Wind Sensor Material: aluminum alloy, polycarbonate Output signal: 4-20mA Wind speed measurement range: 0-30 m / s Accuracy of wind speed measurement: 1 m / s Response time:
