Product Overview

This product is primarily made of high-quality polymer carbon fiber material, offering excellent anti-corrosion and anti-erosion properties, ensuring long-term rust-free operation of the instrument. Combined with an internal smooth bearing system, it guarantees the accuracy of information collection. Its compact and lightweight design makes it easy to carry and assemble, while the three-cup design concept enables the acquisition of external environmental information.

Features

◆ Small size, easy to carry, simple installation

◆ Four fastening screws enhance support, allowing monitoring of stronger winds

◆ High measurement accuracy, wide range, excellent stability

◆ Reasonable structural design, high-quality appearance

◆ Good data linearity, long signal transmission distance, strong resistance to external interference

Working Principle

When the wind cups rotate, they drive a coaxial multi-tooth chopper disc or magnetic rod to rotate. The circuit generates a pulse signal proportional to the rotation speed of the wind cups. This pulse signal is counted by a counter and converted to obtain the actual wind speed value.

Application

Can be used for wind speed measurement in environments such as greenhouses, environmental protection, weather stations, ships, docks, and aquaculture.

Mounting Method

Uses a flange mounting method. The threaded flange connection securely fixes the lower pipe fitting of the wind direction sensor to the flange plate. The base plate has a diameter of Φ65 mm, with four Φ6 mm mounting holes evenly distributed on a Φ50 mm circle. Bolts are used to firmly fix it to the bracket, keeping the entire instrument level to ensure the accuracy of wind direction data. The flange connection is convenient to use and can withstand high pressure.
