AQ Wind Monitor Description：

User's manual Replacement Parts

The YOUNG Model 05305 Wind Monitor-AQ measures horizontal wind speed and direction. Adapted from our Model 05103, this sensor is designed to meet many air quality specifications. A lightweight, carbon fiber thermoplastic (CFT) helicoid propeller, used to measure wind speed, generates an AC sine wave signal upon rotation. Wind direction is determined by a lightweight, balanced, 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. The sensor mounts on a standard 1-inch IPS pipe. A mounting orientation ring is included that engages with the base of the sensor to retain orientation when the sensor is removed for maintenance. 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 Monitor-AQ is also available with 0-5 VDC outputs, Model 05305V, or 4-20 mA outputs, Model 05305L (both models scaled for 0-100 m/s and 0-360 degrees). The 05305L 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.
