SPAS Ultrasonic Anemometer 2 axis, 15cm Probe

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.

Features: No moving parts Digital outputs Time proven design Sensor emulation Replaces many other anemometers Low power Solid-state digital operation	Extras: Mounting Fixture – Allows for mounting to the end of a horizontal pipe, 1” IPS Materials – Anodized aluminum and stainless steel Environment - Capable of withstanding hostile environmental conditions Connections – A single connector on the bottom provides input power and output signals
