Anemometer Mechanical three cup wind speed direction sensor for weather station 4-20mA/RS485/Modbus

The integrated wind speed and direction sensor consists of a wind speed sensor and a wind direction sensor. 

The wind speed sensor adopts the traditional three-cup wind speed sensor structure, and the wind cup is made of carbon fibre material with high strength and good start-up.

The signal processing unit inside the cup can output the corresponding wind speed signal according to the user's needs. The wind direction sensor adopts a precision potentiometer and a low-inertia light metal wind vane to respond to the wind direction, with good dynamic characteristics.

Integrated wind speed and direction sensor application scenarios：

The product has the advantages of large measuring range, good linearity, strong resistance to lightning strikes, convenient observation, stability and reliability, etc.

It can be widely used in meteorology, marine, environment, airport, port, laboratory, industry and agriculture and transportation.

One-piece wind speed and direction sensor installation：

When installing the sensor, please ensure that the wind direction sensor is on the top and the wind speed sensor is on the bottom, and that the sensor is installed in a vertical direction to the ground, there is a white fixing point on the wind direction sensor, please refer to the compass included with the product to keep the wind direction guide direction in line with the geographical south before use.

Troubleshooting ：                                

   1、The wind vane rotation is not working, the hysteresis is big. May be due to long-term use There are foreign objects in the bearing or the lubricant is used up. Please fill the instrument oil from the upper bearing of the sensor or send the sensor back to the company for oil injection.  The oil should be injected from the upper bearing of the sensor or the sensor should be returned to the company.

   2. When the analogue output is used, the display shows a value of 0 or not in range. 2. When the analogue output is displayed, the display shows a value of 0 or not within range. It is possible that the collector is not getting the correct information due to a wiring problem. Check that the wiring is correct and secure. Please check that the wiring is correct and secure.

   3、If not for the above reasons, please contact the manufacturer.

Integrated wind speed and direction sensor is composed of wind speed sensor and wind direction sensor, wind speed sensor adopts the traditional three wind cup wind speed sensor structure, the wind cup is made of carbon fiber material, high strength, good start-up;

The signal processing unit inside the cup can output the corresponding wind speed signal according to the user's demand, and the wind direction sensor adopts a dense potentiometer inside, and chooses a low inertia light metal wind vane to respond to the wind direction, with good dynamic characteristics.

Integrated wind speed and direction sensor products have the advantages of large range, good linearity, strong resistance to lightning strikes, convenient observation, stability and reliability, etc., can be widely used in meteorology, marine, environment, airports, ports, laboratories, industry and agriculture and transportation and other fields.
