Dyacon Wind Sensors: Product Introduction

Wind sensors are critical pieces of weather instrumentation for the professional and amateur meteorologist…and for anyone involved in an industry in which weather plays a role. To be effective, wind sensors must provide accurate and reliable data with regard to wind speed and direction, and then present that data in a usable format. Dyacon wind sensors, both the Modbus-compatible and specialized data interfaces (SDI-12), are designed to this end.

Where is wind speed used? When we think of wind speed, we might think of the weatherman. While wind speed is indeed an important component of meteorology, it also plays a vital role in many other industries, including but not limited to agriculture, construction, aviation, and shipping. Tracking, recording, and analyzing wind speed can provide answers and solutions to challenges that arise in areas such as forecasting weather, determining safety of equipment operations (e.g., cranes, lifts), monitoring a wind farm’s efficiency, maximizing safety in aircraft takeoff and landing, and others.

Is wind direction important? Why? Tracking wind direction provides an indication of weather changes and storm front movement. Wind direction data may also be useful in evaluating vulnerability of assets, such as industrial equipment, structures, airplanes, or crops. The measurement of wind speed without wind direction is about as useful as driving directions that say, “You’ll arrive at your destination if you drive 75 mph for 1 hour.” Obviously, the direction is critical to the applicability of speed measurements. 
How are data accessed from a Dyacon wind sensor? Dyacon digital output wind sensors are available in two flavors: Modbus RS-485 or SDI-12. The Modbus version can be used with Dyacon MS-100 weather stations or standard industrial automation controllers, such as programmable logic controllers (PLCs). PC applications may also be used to capture Modbus data. Those involved in forestry, meteorology, or hydrology often use SDI-12 sensors with environmental data loggers.
The digital output not only provides wind speed and direction, but it also includes enhanced data for 2 minute and 10 minute averages, as well as wind gust. The enhanced data ensure accurate and real-time information while minimizing the tasks required of the data acquisition device. 

What physical features make Dyacon wind sensors useful? Dyacon wind sensors are made in the USA from 6061 machined aluminum and are designed as a rugged package, able to withstand wind speeds in excess of 75 mph (120 kph). Anemometer cups are injection molded out of UV-stabilized polycarbonate.
Wind sensors include the following features: outdoor-rated, shielded cable; hybrid stainless steel and ceramic bearings; no-contact direction sensor; no-dead-spot direction sensor; and field-replaceable vane and cup components. The wind sensor is installed with standard 1” structural pipe fittings. The slim mechanical construction minimizes snow accumulation, thereby improving data accuracy and instrument longevity.
