Wind Speed Sensor With Analog Output – 3S-WS-I-A
Wind speed sensor, also known as anemometer, is one of weather station sensors. This Sensor measures wind speed by converting it into an electrical signal in m/s. The Wind Speed Sensor is designed to measure horizontal wind speed independently of direction. The measuring electronic element in the wind speed sensor is the reed relay driven by the rotating magnet connected to the wind bowls.The Wind Speed Sensor with Analog Output is compatible with all Dataloggers, Gateways, and PLCs with Analog input port. It is supplied with mounting facility and cable. Heating option is available for locations where there is a risk of icing.
What is Wind Speed Sensor and how does it work?
One of the key parts of weather monitoring stations, the anemometer—also called the wind speed sensor—is vital to the analysis of environmental conditions. After measuring wind speed, this sensor transforms the result into an electrical signal in meters per second (m/s). Its design allows it to measure horizontal wind speed without regard to wind direction. Because the housing is composed of anodized aluminum that is resistant to seawater, the sensor is incredibly resilient and long-lasting. There is also a transducer in the box, and it called transducer box.
With the finest price/performance ratio, it is the best option for meeting the standard criteria of environmental and industrial applications, including photovoltaic plants. The Wind Speed Sensor with analog output is compatible with all Dataloggers, Gateways, and PLCs with 4-20 mA output.

What is the importance of Wind Speed Sensors?
IEC 61724-1:2021 states that wind speed is crucial for substantiating warranty claims for wind-related damage in addition to being utilized for determining module temperatures. More specifically, wind is a crucial factor for structural safety and can indirectly alter system efficiency by influencing module temperature. Wind sensors, for instance, evaluate the possibility that panels will be harmed by strong winds. Systems that support loads may sustain damage from excessive wind. We can therefore utilize the wind speed sensor as proof of excessive wind for such damages.
How to install the wind speed sensor?
There is two different mounting method for installation: pipe and ground mounting. These mounting methods are explained in more detail below.
