Switching Current: 10 mA

Series Resistance: 330 Ω, 1 W

Operating Temperature: –35° to 60°C

7. Installation

Locate wind sensors away from obstructions (e.g., trees and building). As a

general rule, there should be a horizontal distance of at least ten times the

height of the obstruction between the wind set and the obstruction. If mounting

the sensors on the roof of a building, the height of the sensors above the roof

should be at least 1.5 times the height of the building. See Section 10 for a list

of references that discuss siting wind speed and direction sensors. For power

performance applications, refer to IEC 61400-12-1 which specifies the

mounting and location of anemometers.

7.1 Wiring

Connections to Campbell Scientific dataloggers are given in TABLE 7-1 and

TABLE 7-2. When Short Cut program generator software is used to create the

datalogger program, wire the sensor to the datalogger as directed by the wiring

diagram created by Short Cut.
