Guide you to understand ultrasonic wind speed and direction sensors

Introduction

RIKA SENSOR's RK120 - 03 Ultrasonic Wind Speed and Direction Sensor is a remarkable addition to the field of wind measurement devices. With OEM/ODM services available, it offers flexibility to a wide range of customers. This sensor is designed to meet the diverse needs of various industries that require accurate and reliable wind data.

What is a Ultrasonic Wind Speed and Direction Sensor?

An ultrasonic wind speed and direction sensor like the RK120 - 03, is a sophisticated device that utilizes ultrasonic technology to measure wind - related parameters. It operates based on the principle that the speed of ultrasonic waves traveling through the air is affected by the movement of the wind. By measuring the time it takes for ultrasonic signals to travel between different transducers in multiple directions, the sensor can calculate both the wind speed and direction. This non - mechanical approach, free from moving parts, provides several advantages over traditional anemometers.

Why Use an Ultrasonic Wind Speed and Direction Sensor?

In many applications, precise wind data is crucial. In meteorology, accurate wind speed and direction measurements are fundamental for weather forecasting. The data helps meteorologists predict weather patterns, storms, and changes in atmospheric conditions. In oceanography, understanding wind conditions is essential for studying ocean currents, wave formation, and marine ecosystems. For the transportation industry, especially in airports and ports, wind information is vital for safe take - offs, landings, and ship maneuvering. In industrial and agricultural settings, wind data can be used for ventilation control in factories and for optimizing crop irrigation systems.

Product Highlights

• High - Precision Measurement: The RK120 - 03 offers excellent accuracy. For wind speed, it has an accuracy of ±0.2m/s when the speed is ≤10m/s and <±2% of the current value when >10m/s. The wind direction accuracy is ±3°. With a resolution of 0.01m/s for wind speed and 1° for wind direction, it can detect even minor changes in wind conditions.

• Low Starting Threshold: With a starting threshold of just 0.1m/s, this sensor can detect very gentle breezes. This makes it suitable for applications where even the slightest wind movement needs to be monitored.

• Durable and Lightweight Design: The sensor is made with a combination of carbon fiber and ASA material. The overall carbon - fiber construction contributes to its lightweight nature, with an unpacked weight of only 0.8kg. At the same time, it has a strong corrosion - resistant ability, allowing it to withstand harsh environmental conditions. Its IP66 ingress protection rating ensures that it can resist dust and water ingress, making it suitable for use in various weather conditions.

• Versatile Output Signals: It offers multiple output signal options, including RS232/RS485 (compatible with Modbus/NMEA - 0183) and 4 - 20mA (specifically for wind speed and direction). This allows for easy integration with different monitoring systems, whether they are based on analog or digital technology.

• Wide Operating Range: The sensor can operate in a temperature range of -30℃ - +70℃. It also has an optional heating function with a maximum power of 3W, which can be activated in cold environments to prevent icing and ensure reliable operation. Additionally, it can measure atmospheric pressure (with a range of 150 - 1100hPa, resolution of 0.1hPa, and accuracy of ±1 hPa) and has an optional electronic compass, providing more comprehensive environmental data.

Application and Necessity

• Automatic Weather Stations: The RK120 - 03 is an ideal choice for automatic weather stations. It provides accurate wind data that is essential for generating comprehensive weather reports.

• Drilling Platforms and Ports: In these industrial settings, wind speed and direction information is critical for safety. It helps in the operation of equipment on drilling platforms and for the safe navigation of ships in ports.

• Ships: On - board ships, the sensor enables sailors to make informed decisions regarding navigation and the operation of sails or engines, depending on the wind conditions.

• Tunnels and Scenic Spots: In tunnels, wind monitoring is necessary for ventilation control. At scenic spots, wind data can enhance the safety of visitors and also be used for environmental research.
