Wind Speed Sensor With Modbus RTU Output – 3S-WS-MB-A
Small and economical Anemometer used for measuring Wind Speed in a Solar PV Plant. The Output Signal is Modbus RTU and it is compatible with all Modbus RTU dataloggers. It is supplied along with Cable.
What is Wind Speed Sensor and how does it work?
The anemometer, commonly known as the wind speed sensor, is an essential component of weather monitoring stations and is used to analyze environmental conditions. This sensor converts the wind speed measurement into an electrical signal in meters per second (m/s). Because of its design, it can measure horizontal wind speed regardless of the direction of the wind. The sensor is very durable and long-lasting because the housing is made of anodized aluminum, which is resistant to seawater. There is also a transducer in the box, and it called transducer box.
It is the ideal choice for satisfying the standard requirements of industrial and environmental applications, including photovoltaic plants. Wind Speed Sensor with Modbus RTU Output is compatible with all Modbus RTU dataloggers. It is also supplied along with cable.

What is the importance of Wind Speed Sensors?
In addition to being used to determine module temperatures, wind speed is essential for supporting warranty claims for wind-related damage, according to IEC 61724-1:2021. More precisely, wind can indirectly change system efficiency by affecting module temperature and is an essential component of structural safety. For example, wind sensors assess the likelihood that high winds will damage panels. For such damages, we can use the wind speed sensor as evidence of severe wind.
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.
Why Choose SEVEN Wind Sensors?
High Sensitivity: Made to offer optimal sensitivity even in difficult and windy conditions.
