Vector - Model A100 - Anemometer
The wind transmitter is used the registration of he horizontal component of the wind velocity. The measuring value will be placed at the output as digital. The signal can be given to date logger. The wind transmitter is equipped with an electronically regulated heating system in order to prevent icing of the ball bearings and the outer rotating parts. Power supply unit provides the transmitter and the heating system with current. It is advisable to attach a lightning rod in areas with considerable lightning activity.
Construction and Mode of Operation
A low-inertia light plastic cup star is set into rotation by the wind. Through the opto electronical-rotating-frequenzy-scanning the resulting pulse frequency is used for the digital data p processing. Input and outputs have to protected from overload by transzorb diodes. The outer parts of the Instrument are made of corrosion-resistant parts and they are protected through a varnish. The wind transmitter is shipped in a semi-mounted state in order to avoid transport damage and to keep the package small.
Selecting the measuring location
The anemometer should ideally be mounted at the top of a mast to be open to the wind from all directions. Only a lightning protection rod mounted below may overtop the sensor.
For the protection of the giver it is urgently necessary to secure the mast with a lightning protection staff and appropriate grounding measures professionally. The standard instrument is designed to withstand all weather conditions; many thousands being in continuous use at all latitudes around the world. Marine versions are available and heaters can be fitted to prevent icing of the bearings.
