Model SPAS/2Y Style -Sonic Anemometer
The “SPAS/2Y style sonic anemometer is a 2 axis, 15 cm Ultrasonic Anemometer. This sensor offers high quality performance in an less expensive package. The electronics are contained within the probe and a single cable connects it to your PC. This sensor can provide the same accuracy and resolution of the scientific Ultrasonic Anemometer, with the exception of the mechanical direction. This probe is designed to meet the needs of ultrasonic anemometer users. This meteorological instrument can be used in many different weather systems for accurate wind speed, wind direction and temperature information.
The Model SPAS/2Y Solid State Wind Sensor is an improved and more precise 2D member of Applied Technologies, Inc.’s Sonic Anemometer product line. This sensor offers high quality performance in a less expensive package. The SPAS/2Y Wind Sensor is a continuation of the Sonic Wind Sensors developed 30 years ago, and contains the same wind distortion algorithm and factoring that have been proven and accepted around the world.
Data from the instrument is digital for direct connection to data loggers, computers, and systems. The instrument is designed to perform.
