Classic Wind Speed Sensor

Model 4.3303.22.xxx

The Classic Wind Speed Sensor measures the horizontal wind speed with an analogue output which can be transmitted to a display, recording instrument, datalogger as well as a process control system. For winter operation the sensor is equipped with electronicaly regulated heating  to guarantee the smooth running of the ball bearings and to avoid ice formation at the slot of the outer rotating parts. The electrical supply of the sensor heating is provided by a power supply such as model 9.3388.00.000. It is advisable to attach a lightning rod (model 4.3100.99.000) in areas with considerable lightning activity (see Accessories tab).

The housing of the cup star and wind vane are made of anodised aluminium and the bow is stainless steel. Labyrinth seals and o-rings protect the sensitive internal parts from precipitation. The instrument is designed for mounting to a mast tube and the electrical plug connection is situated in the transmitter shaft.

How it works

A low inertia light metal cup star (in ball bearings) is set into rotation by the wind. The opto electronic revolution scanning produces a pulse frequency which is transformed into the analogue signal by means of an integrated measuring transducer.
