HD2003.1 Ultrasonic Anemometer:

HD2003.1 are three-axis ultrasonic, static anemometer for measuring wind speed and direction, U-V-W Cartesian Components of speed, wind gusts, sound speed, and sonic temperature. Five different analog voltage or current outputs for different ranges. Communication software for two-way connections for network connection of different anemometers, interfaces available RS232, RS485, RS422.Different measuring units and average periods are available. Transducer heating as optional. 12.. 30 Vdc power supply, 120 MA consumption at 15Vdc. To be mounted on a mast diam. 33mm. Flying connector included.

When ordering, if the expansion of analog outputs is necessary by additional external sensors with 0 1V analog output. In order to line up their range of the 0 1V scales, you must specify in this case the number of sensors you intend to use (max. five), and their physical range.
