What are the core parameters (range, accuracy, output) of the RK120-03 Ultrasonic Wind Speed & Direction Sensor?

The rk120-03 is a high-performance sensor utilizing advanced ultrasonic technology. It is specifically designed for users seeking the weather sensors best suited for maintenance-free operation in professional deployments. Adopting a solid-state design without mechanical moving parts, it is suitable for outdoor wind monitoring needs in various fields such as meteorology, transportation, ports, photovoltaics and agriculture. The core key parameters such as power supply, measuring range, accuracy and output interface of the device are professionally and flexibly configured, supporting standard configuration and personalized optional selection. The specific detailed parameters are as follows:

• Wind Speed: A standard range of 0-45m/s, customizable up to 0-60m/s with nearlyzero startup wind speed. Accuracy is outstanding: +0.2m/s when wind speed is 10m/s, and +2% of the reading when wind speed is > 10m/s.
• Wind Direction: Provides full 0-360° coverage with an accuracy of +3°.
• Optional Parameters: Can be integrated with a high-precision Barometric PressureSensor (150-1100hPa, accuracy 士1hPa).

• Low Power Consumption: Operates on 12-24V DC. Standby power is less than 1W,making it ideal for solar-powered weather station systems in remote locations.
• Intelligent De-icing/Anti-fog: Equipped with an automatic internal heating module(total power < 3W during heating), ensuring continuous data transmission bypreventing ice or fog accumulation in extreme arctic or mountainous environments.

To ensure seamless integration with various PLCs, data loggers, or loT platforms, thisenvironmental sensor offers multiple output options: standard RS485 (Modbus-RTU), optional RS232 (NMEA-0183), or 4-20mA analog output.
