Anemometers (Windspeed)

High specification anemometer.  Marine versions are available, as are heating elements

  • An anemometer for run of wind measurements, or operation with an electronic counter to determine average wind speed.
  • A magnet turns with the rotor spindle and the resulting varying field causes a mercury wetted reed switch to make and break contact once per revolution of the rotor.
  • The contacts are bounce free, simplifying connection to electronic circuits, and no power is required apart from that necessary to detect contact closure,
  • Suitable for permanent exposure to the weather.
  • In the marine version (A100/WR) a touching shaftseal is fitted for extra protection in place of the standard non-contact seal, with a small increase in threshold speed.
  • An anti-icing heater can be fitted if required facilitating use at remote sites
