Increase the performance of your wind turbines!
When technical systems are exposed to permanent environmental influences and extreme weather, changes in the environment must be registered comprehensively, accurately and reliably in order to protect people and machinery from damage and destruction.
Extreme temperatures, humidity, storms or hail can impair the function of such systems. KRIWAN wind sensors safely withstand climatic and mechanical influences and ensure the operational reliability of the systems even under extreme weather conditions.
Specially adapted to different applications, various wind sensors are available. From simple application areas with unheated sensors to our standard sensors with heating for industrial applications and meteor sensors for demanding meteorological applications.
Precise measurement in wind and weather
ICEfight in actionThe KRIWAN wind sensors are characterized not only by their high quality, but also by the large variety, which enables our customers to find the right anemometer or the right wind vane for their respective area of application. We offer wind sensors with mast mounting, central mounting or pendulum mounting. As connection variants, we offer plugs or cables as well as a combination of both variants.

For the use in extreme weather conditions, for example at high altitudes. The heater integrated into the cup star or vane enables trouble-free operation even in freezing rain.
KRIWAN anemometers and wind vanes of the ICEfight series are used wherever, in addition to the demanding detection of wind speed or wind direction, trouble-free operation must be ensured even under the most difficult environmental conditions, especially where there is an extreme risk of icing at very low temperatures.
This requirement applies in particular:
A heater with ample capacity, to which electrical power is fed contact-free and lossless from the fixed part of the sensor, is located inside the anemometer cup or the vane. Because this heater extends out to the extremity of the anemometer cup or vane, all parts of the anemometer cup or vane are heated with a high efficiency. At ambient temperatures at which icing can develop, the heater turns on and this nearly excludes any likelihood of icing at the hooked up heater within the approved ambient temperatures. The temperature of the heater is monitored, and the heater switches itself off autonomously at high surface temperatures.

Special offshore wind sensors have been developed for the use on the open sea. The offshore anemometer and the offshore wind vane are characterized by a salt fog resistant special coating.
For the use on the open sea as well as onshore under particularly corrosive environmental conditions such as salt spray and fog. KRIWAN anemometers and wind vanes are used for sophisticated detection of wind speed and wind direction, e.g.
The KRIWAN anemometer INT10 OF records the actual wind speed and transforms it contact-free into a linear output signal. The KRIWAN INT30 OF wind direction sensor records the current wind direction and also converts it into a linear output signal without contact. The sensors are designed to be storm- and weather-proof. Due to the self-regulating heating, use down to -40°C is possible. The evaluation is carried out separately via a measuring device, a display instrument or in the connected control and monitoring technology.

For particularly demanding environmental conditions with increased contamination potential. The specially sealed bearing enables use in dusty environments.
KRIWAN anemometers and wind vanes of the Heavy Duty series are used to record the wind speed or wind direction under difficult environmental conditions. Trouble-free operation must be ensured even under the most difficult environmental conditions, especially where there is an extreme risk of icing at very low temperatures. Suitable for the use in dusty environments due to specially sealed bearings.
This requirement applies in particular:
The KRIWAN anemometer of the Heavy Duty series is used wherever, in addition to the sophisticated detection, the KRIWAN anemometer detects the current wind speed and converts it into a linear output signal without contact. The sensor is storm and weatherproof. The evaluation is done separately via a measuring device, a display instrument, or in the connected control and monitoring system. Within the cup anemometer is a generous dimensioned heating, which is supplied without contact and mechanically lossless from the stationary sensor part with electrical energy. As this heater extends to the ends of the cup anemometer, all parts of the cup anemometer are heated highly efficiently. At ambient temperatures at which ice may form, switch on the heater, icing with connected heating and within the permitted ambient temperature is almost impossible. The heating is temperature-controlled and switches off automatically at too high surface temperatures.
