Wind Speed & Direction Sensor - MBMet-130

MBMet‑130 is a high-precision, dual-parameter wind sensor

The MBMet‑130 is a high-precision, dual-parameter wind sensor designed to measure both horizontal wind speed and wind direction in a single compact unit. It combines a durable 3-cup anemometer and a 360° wind vane mounted on the same vertical axis, offering consistent and synchronized wind data from a single point of installation. This architecture simplifies deployment while ensuring accuracy and reliability in various industrial and meteorological applications.
Constructed using carbon-fiber reinforced plastic and aluminum alloy, and rated IP65, the MBMet‑130 is engineered for harsh weather conditions and long-term outdoor exposure. With options for both analog (4–20 mA) and digital RS‑485 Modbus RTU output formats, it integrates seamlessly with modern SCADA systems, data loggers, and weather monitoring platforms.
