The Dwyer Instruments Model 9671 Anemometer is a versatile and accurate wind measurement instrument designed for various applications in industries such as HVAC, process control, and meteorology. This anemometer is capable of measuring wind speeds within a range of 0 to 118 miles per hour (0 to 190 kilometers per hour) with a full-scale deflection of 140 degrees.
The heart of this anemometer is a 3-blade propeller rotor, which is driven by wind and converts wind energy into electrical signals via a magnetic pickup system. The unit comes equipped with a robust, watertight, and corrosion-resistant housing made of die-cast aluminum, ensuring its durability and reliability in harsh environments. The housing is also UV-stabilized to withstand prolonged sun exposure.
The Model 9671 Anemometer features a large, easy-to-read, 3.75-inch (95.25 mm) diameter dial that displays wind speed in miles per hour and kilometers per hour. The dial has graduations every 1 mile per hour (1.6 kilometers per hour) and every 5 miles per hour (8 kilometers per hour), making it simple to obtain accurate readings. The unit also includes a built-in temperature sensor, which measures ambient temperature and compensates for temperature effects on wind speed readings.
The anemometer is designed for easy installation and can be mounted on a wall or pole using the included bracket. The power source can be either a 100-240 VAC power supply or 24 VDC power supply. The unit is also compatible with Dwyer's DataLogger DL2000 and DL2500 data loggers for remote data collection and analysis.
In summary, the Dwyer Instruments Model 9671 Anemometer is a high-performance wind measurement instrument that offers accurate, reliable, and easy-to-read wind speed readings in various applications. Its robust and corrosion-resistant housing, large and easy-to-read dial, and compatibility with various power sources and data loggers make it an excellent choice for industries requiring wind measurement capabilities.
