Wind direction - 13N-230

The equipment is used to survey wind direction. The instrument is equipped with a self regulating heating, NTC model, against frost. The signal recording is optical. By an internal electronic appliance, the optical signal is changed in a 2 wires signal, independent from polarity. 16 directions can be recorded. Wind direction is calculated by the absorption system current.
