The 200-500 Wind Speed Dial displays wind speed from 0 to 100 mph and 0 to 160 km/hr. In addition to indicating instantaneous wind speed, the dial needle moves a gust register needle to indicate the maximum gust since the last needle reset.
The 200-WS-21-A Dual Set Point Wind Alarm is a microprocessor-based wind alarm system. It sounds an alarm and controls the operation of two electrical circuits whenever wind speed reaches either of two independently set limits. It has 0 to 100 mph wind speed measurement and alarm range. A liquid crystal display provides a readout of the measured wind speed, maximum wind speed, and it is also used to display the menus for the user to select the alarm parameters.
