Wind Activated Switches
nstromet`s range of wind switches is slowly growing in popularity and is rapidly finding its way into many applications such as use with de-odourisors, water fountains, inflatable outdoor products, lighting rigs, air recirculation fans just to name a few. The range of wind switches comes in the form of two main types, versions for wind speed only and versions for wind speed and wind direction.
The attached chart gives a summary of the type of wind switches we produce along with their respective features for each model. wind switch selection chart...
The below rollover images give examples of the various switches available:
Each comes supplied with operating control box, appropiate wind sensor inc 25m of cable (extendable up to 100m on request), and wind sensor alignment compass.
Each unit has controls for selecting the wind speed activation point up to 90mph. They also incorporate an "on" timer to prevent premature switching due to short sharp gusts, and also an "off" timer to ensure the exceeded wind conditions have truely rescinded. The wind switch models that include wind direction also have eight selectable switches for each main compass point. These particular wind switches will only activate once specifically set wind direction and wind speed conditions have been met.
The actual switching capabilities of the control box is performed by a relay capable of handling a 5A load. This relay has three terminals and can either be used in a "normally closed" configuration or a "normally open" configuration. This of course means it can be used to either activate a peripheral device or de-activate a peripheral device.
As Instromet hand builds these wind switches on site, we are able to offer different scaling and time delay parameters on request. Likewise if you feel a slightly different version of wind switch would be more suited to your application then please consult us to see if we can produce a version to suit.
