  Brownout Prevention
High winds can sway power lines, often causing brownouts. Working with an engineering firm, we integrated our Wind Speed Alarm into a control panel which re-routes electricity within the electric grid
when high winds occur. Wind Speed Alarm, in conjunction with this re-routing device, has helped reduce the frequency of brownouts caused by high winds.
Security / Observation Platforms
Wind Speed Alarm was designed into the elevation controller for mobile observation platforms. When
winds exceed the specified levels, the alarm’s relay triggers a device that lowers the platform to a safer
level.
Agriculture
Large tarpaulins are used to cover grain supplies and keep them from suffering water damage. During high winds, these tarps can be secured with the turn of switch. Wind Speed Alarm provided a reliable method for performing this task while saving the expense of 24/7 power and a human operator.
Fountain Control
Wind Speed Alarm was integrated into a fountain controller to regulate fountain operation based on wind speed. If the system continually turned off and on there was the possiblity of damage to the controller. An accessory was developed for Wind Speed Alarm that prevents this power cycling from taking place. At a certain wind speed the fountain will now shut down until it is manually reset.   Many crane work sites are required to maintain an accurate reading of wind speed and a method for taking quick action to prevent damage and/or injury. Maximum works with several manufacturers to develop methods for incorporating our Wind Speed Alarm into new and existing crane models.
