The sensor is designed according to WMO (World Meteorological Organization) standard and is usually provided with standard digital output RS485 or 4÷20mA on request. This sensor is suitable for applications in various fields of environmental monitoring and is particularly indicated for the AWOS weather stations in the aeronautical installations. Easy to install, it requires no periodic calibration and is protected from overvoltage and corrosion. The sensor is designed for pole mounting with two adjustable collars.
