ANEMO4403 | 4 - 20 mA

Anemometer for industrial application

Plastic Rotating Anemometer with Reed contact

Anemometro industriale

A simple, reliable and robust for heavy use in industrial environments. The special shock-resistant materials used in the construction of the rotor and the use of special bearings, give this speed sensor unique characteristics of great mechanical strength and high accuracy in the detection of wind speed.

The Anemometer ANEMO 4403 has been specifically designed for industrial applications such as: 

  • Cranes and Mobile Cranes
  • Buildings and general structures
  • Photovoltaic solar trackers
  • Weather Stations
  • Irrigation systems
  • Automated greenhouses
  • Cable cars for ski plants
  • Cannons snow
  • Telescopic cranes
  • Platforms self-mounting
  • Structures for playgrounds
  • Ornamental fountains
  • Pressostatic structures
  • Highway tunnels and viaducts

It can be connected through the various outputs available depending on the model directly to PLC and / or board electronic market, tachometers WM44P as the model of our product range.

Model with connector



Model 120km/h up to 120 km/h of the wind.
Model 180km/h up to 180 km/h of the wind.

With a power supply of 12 Vdc the maximum load is 275 ohm.
With a power supply of 24 Vdc the maximum load is 560 ohm.
Output: analogic proportional 4-20 mA


Relation Wind speed / Output.
The output current is proportional to the wind speed.

Model F.S. 120km/h
Wind speed
= 0Km/h->Output Anemo4403 = 4 mA.
Wind speed = 120Km/h->Output Anemo4403 = 20 mA

Model F.S. 180km/h
Wind speed = 0Km/h->Output Anemo4403 = 4 mA.
Wind speed = 180Km/h->Output Anemo4403 = 20 mA
