MODEL 200-05103 / 200-05305 : Wind Sensor

General Description

The Model 200-05103 and Model 200-05305 Professional Wind Sensors provide reliable information about wind speed and wind direction even in harsh environments. Simplicity and lightweight corrosion resistant construction were principal design considerations. Slip rings and brushes have been eliminated, resulting in improved reliability with lower cost. Modern thermoplastic materials improve resistance to corrosion from sea-air environments and from atmospheric pollutants.

The instrument mounts on standard 1 inch pipe, outside diameter 34 mm (1.34 in.). An orientation ring is supplied for maintaining wind direction orientation when the instrument is removed for maintenance.

The Model 200-05103 General Purpose Wind Sensor can be used with indicators, recorders, data loggers, or personal computers to fulfill a wide range of wind measuring or complete weather station requirements. Its sensitivity satisfies general purpose requirements for wind monitoring.

The Model 200-05305 Air Quality Wind Sensor has added sensitivity for tracking lower wind movement. This sensor meets most U.S. Government Agency guidelines for wind monitoring.
