Ultrasonic wind speed and direction sensor RS485/MODBUS

Product introduction of small ultrasonic wind speed and direction sensor

 The mini small ultrasonic wind speed and wind direction sensor is a mini fully digital sensor, highly integrated ultrasonic wind speed and wind direction sensor, small size, high integration, light weight, strong and durable;

This product does not have any moving parts, and does not require on-site maintenance and calibration. It can accurately and quickly detect the wind speed and wind direction values in the on-site environment. The high-strength structure design can accurately detect in harsh climate environments, and can be widely used in agriculture, meteorology, environment , environmental protection, transportation, smart city, industrial testing and other fields.

Ultrasonic wind speed and direction sensor installation precautions:

The mini ultrasonic wind speed and direction sensor can meet many specifications and can be used in different environments around the world without complex maintenance and calibration on site.

1. Check frequently to ensure that the sensor is not interfered with by other running equipment, which may not fully comply with common standards, such as radio/radar transmitters, ship engines, engines, etc.;

2. Do not install it on a plane with any radar scanning device, at least keep a distance of more than 2M;

3. It is recommended to keep a distance from some surrounding radio receiving antennas;

4. Use the cables recommended by our company;

5. If there is no correct connection after the cable is cut, or the cable shield is not properly connected, there is no need to create a grounding loop, and the wiring can be performed according to the installation instructions;

6. Ensure that the equipment is continuously powered during operation;

7. Avoid flocculation generated by surrounding buildings such as trees, utility poles, tall buildings, etc., which can affect the accuracy of the ultrasonic anemometer;

The installation method of ultrasonic wind speed and direction sensor is as follows:

Positioning: Generally, the equipment is installed on a vertical installation pipe to ensure the measurement on the same horizontal plane;

For indoor use, the sensor can be installed in any desired direction, and the meteorological instrument measures the wind speed and direction on different wind surfaces;

Alignment: The detector should be fixed with the pointing point pointing north.

Note: During installation, it is ideal to use a standard compass to determine the geographic North Pole direction, and to keep the instrument's north pointing direction consistent with the compass direction;

Installation: The installation pipe needs 3 equidistant holes, tap M5 screws, the position is 7.5mm from the top of the pipe, and pass the cable through the installation pipe;
