Lambrecht PRO-WEA Anemometer

The Lambrecht PRO-WEA anemometer is a professional instrument for measuring wind direction and speed, even in extreme environments and resistant to the marine environment . This model is also specially designed to withstand frequent electric shocks , especially in environments prone to storms.
It consists of a vane for measuring wind direction and cups for measuring speed. It is a heated equipment, also designed to withstand mountain conditions and cold climates and is connected to the general current with an intensity between 4 and 20mA.

The weather vane is made of aluminum resistant to extreme weather conditions, with gusts that can exceed 360km / h and numerous electric shocks. It has a sensitivity or precision of +/- 2º . It has heating with a very effective energy saving system.

The cups are also built with the best aluminum and an extra-reinforced axle, resistant to weathering and wind speeds up to more than 220km / h (60m / s) . The accuracy of the equipment is +/- 0.3m / s (up to 10m / s) +/- 0.5m / s at higher speed, with a starting value of 0.5m / s and a resolution of 0.1m / s . It has heating with a very effective energy saving system.


Both the vane and the cups include 15m of output cable , the electrical connection is required for the heating system and data recording. Mounting poles or crossbars not included.

We found 2 different models of the PRO-WEA anemometer:
