RK120-07-AAC is a wind speed and direction meter which uses the time difference of ultrasonic waves in the air to measure the wind speed and direction

The RK120-07 uses low-power chip with power consumption of only 0.2W, which is especially suitable for solar or battery powered environment with high power consumption requirements. Due to the adoption of new technology and new process, the structure is more compact and compact. Optional temperature and air pressure module.

 It simultaneously acquires ultrasonic wind speed and direction data . Built-in signal processing unit can output corresponding data on a RS485 Modbus RTU link. Designed with a high-strength compact structure and no moving parts, it can accurately detect wind in harsh environments. No moving parts results in less maintenance required. It consists of accurate & stable components and RS485 Modbus RTU outputs for both wind speed and direction. It is widely used in meteorology, oceanography, airports, ports, laboratories, industry and agriculture, transportation and other fields.

Acting as a Modbus RTU slave both wind speed and direction can easily be provided to a Modbus Master PLC or RTU or SCADA system

Its high performance makes it ideal for all kind of security and control applications in roads, buildings, ski resorts, theme parks, etc.
