03002 Wind Sentry Anemometer & Vane Description：

User's manual

The YOUNG Model 03002 Wind Sentry measures horizontal wind speed and direction. Three lightweight hemispherical cups, used to measure wind speed, generate an AC sine wave signal upon rotation. Wind direction is determined by a vane attached to a precision potentiometer inside an internal housing. UV stabilized plastic with stainless steel and anodized aluminum parts are used in the construction of the sensor. Precision grade stainless steel ball bearings are used for both the anemometer and vane. The sensor mounts on a standard 1-inch IPS pipe. Terminations are made in a junction box at the base of the sensor by small clamp-style connectors (no special connectors are required).

The Wind Sentry is also available with 0-1 VDC outputs, Model 03002V,or 4-20 mA outputs, Model 03002L (both models scaled for 0-50 m/s and 0-360°). The 03002L is recommended for use in high noise areas or for installations with long cables, typically 300 meters (1000 feet) or more, up to several kilometers.

For wind speed only, YOUNG Model 03102 Wind Sentry Anemometer, 03102V Wind Sentry Anemometer (0-1 VDC = 0-50 m/s), and 03102L Wind Sentry Anemometer (4-20 mA = 0-50 m/s) are available separately.
