R M Young Company 81000 ULTRASONIC ANEMOMETER - 3 AXIS

The Model 81000 Ultrasonic Anemometer brings a new level of value to three dimensional sonic anemometry. This low cost unit boasts features and performance ordinarily found on sensors costing much more.

The 81000 measures wind velocity based on the transit time of ultrasonic signals sent between the transducers. Depending on its orientation and magnitude, air flow alters the sonic signal transit time. By measuring the transit time in each direction along all three paths, the three dimensional wind velocity and speed of sound may be calculated. From speed of sound, sonic temperature is derived. Speed of sound and sonic temperature are corrected for crosswind effects.

Measurement data are available as voltage output signals or serial output using RS-232 or RS-485 connections. Both voltage and serial output may be configured for a variety of output formats.

Operating parameters may be edited using ordinary terminal software on a PC. Simple menus make it easy. All parameters are stored in nonvolatile memory.

Superior environmental resistance is achieved by using UV stabilized thermoplastic, stainless steel, and anodized aluminum components. Electrical connections are made via an easily accessible junction box. The unit mounts on standard 1 inch pipe.
