Anemo 4403-RF-BAT

Radio impulsive output Anemometer Wireless

Robust wind speed sensor, extremely resistant and flexible, Suitable for many different application. Stainless steel bearings and high quality technical plastic body and cups. The RF communication compliant to IEEE 802.15.4 standards, operating within the ISM 2.4 GHz frequency band.

Totally Plug & Play system, no configuration needed. More than one equipment can operate in the same enviroment, no risk of interaction/interference.

The Anemo4403 RF, is suitable to be used for any application where it is necessary to accurately detect the wind speed such as: tower cranes, solar panels, greenhouses, wind generators, etc. but needs quick mounting and wireless system.

Wireless Anemometer and Double Display Equipment

It's now possible to combine two displays (WM44P RF & WM44 EVO11 RF) with an ANEMO4403RF in order to read the data received form the wind sensor in several places. Thanks to the total compatibility of the products, it is possible to create any type of combination:

  • ANEMO4403 RF + WM44 EVO11 RF + WM44P RF
  • ANEMO4403 RF + WM44 EVO11 RF + WM44 EVO11 RF
  • ANEMO4403 RF + WM44P RF + WM44P RF

The WM44 EVO11 RF model can be supplied with the Data logger function, with that the data can be extracted and displayed on a computer.
