TBSWV1 SDI-12 Wind Vane

The TBSWV1 is a versatile wind vane with SDI-12 interface. It provides two operation modes. It can either measure momentary wind direction, or measure average wind direction over a configurable logging period.

It is based on a rugged aluminium body with polyester coating. Precision, low friction bearings, a stainless steel shaft, a rotating rain guard and a breather vented cable grommet make it a very reliable device. The use of a magnetic rotary encoder as sensor element eliminates the disadvantages associated with reed switches used in conventional wind vanes.

Optionally, the wind vane can be delivered with an integrated heating for de-icing.
