The Model 024A Wind Direction Sensor is an accurate, durable and economical sensor suitable for a wide range of wind study applications. It is designed for long-term unattended operation in most meteorological environments.

Features

• Range to 100 mph
• Low starting threshold
• Broad temperature operating range
• Built-in alignment and calibration feature
• Accuracy of ±5°
• Stainless steel and aluminum construction

Operation

The sensor incorporates a precision wire-wound potentiometer for accurate resolution of wind direction. The potentiometer is directly coupled to the vane assembly. Variations in wind direction produce a corresponding varying voltage, which lends itself to both digital and analog measurement systems.

Construction

The contruction of the sensor reflects the requirement for reliability and durability. Only the best corrosion resistant materials, such as stainless steel and anodized aluminum are used. The potentiometer meets stringent military specifications for sand, dust, salt spray and fungus resistance. The Model 024 sensor uses a quick-connect sensor cable. Cable length may extend hundreds of feet without affecting measurement performance.
