High performance technology

separador-prod

The 3R UAV01 is a 2-axis ultrasonic anemometer that measures the wind speed and direction with high accuracy and reliability thanks to its advanced technology.

 

It is especially designed to directly replace the Davis VP2 standard wind cups anemometer without needing to use any other component or transmitter apart from a power supply.

3R UAV01 - Ultrasonic Anemometer for Davis VP2 - Installation

To determine the wind speed and direction, the sensor emits ultrasonic pulses from one transducer to the opposite one along 2 orthogonal axis and then measures the elapsed time between the emission and the reception of the pulses. The measurements are done in both directions of each path to avoid errors caused by the current environmental conditions of temperature, humidity and barometric pressure.

 

Its high performance makes it ideal for all kind of security and control applications in roads, buildings, ski resorts, theme parks, harbors, etc. Its low power consumption allows to use it in installations powered by solar panels.

 

Rugged and weatherproof design
