Ultrasonic anemometers can suffer from extreme weather conditions, and in particular the formation of ice on the transducers, a situation in which the anemometer returns incorrect, partial values, or even ceases to function until the ice has disappeared.
In the professional ultrasonic anemometers there is the possibility to heat the sensor, some offer two variants, one normal and one heated for extreme climates, but here we are not dealing with a professional sensor
I can communicate that all the new ws80 will already be equipped with a heating system already installed, the ws80 will be complete with a cable that will be passed through the bracket tube (obviously it has been modified for the purpose), who needs to heat the anemometer can buy the extension cable (10 or 20mt) and network adapter from ecowitt, those who do not need this will protect the connector at the end of the cable with a silicon watertight cover (supplied with the ws80)
the new version will cost exactly as before, so $ 110 excluding shipment costs, e extensions complete with adapter will cost $ 20 for the 10m and $ 35 for the 20m.
I hope it is appreciated and I apologize for my English
