WIND DIRECTION SENSOR

Wind Direction Sensor

Model 023

Model 023 Wind Direction Sensor is a rugged sensor that accurately and reliably measures wind direction under the most adverse environmental conditions.

The Model 023 has been specifically designed for use in remote, unattented monitoring applications where the sensor is likely to encounter high winds and heavy icing conditions. The sensor has a starting threshold of 1.5 mph. Additionally, the sensor has built-in ice skirt which allows operation with up to a 2" ice load.

FEATURES

Low starting threshold of 1.5 mph

Unique "Mechanical Average System" reduces sensor wear

Built in alignment and calibration fixture

Operates in winds of 150 mph and ice loads of 2"

The two part wind vane is connected by a unique ±10° slotted shaft coupler to a precision wire wound potentiometer. The sensor output is an accurate MECHANICAL AVERAGE of the wind direction. An additional benefit of the slotted shaft coupler is decreased potentiometer wear and greatly increased sensor life. The Model 023 includes an orientation fixture which facilitates accurate field alignment.

CONSTRUCTION

The construction of the Model 023 Sensor reflects the requirement for reliability and durability. Only the best corrosion resistant materials, such as stainless steel or anodized aluminum are used. The Model 023 is used with a quick connect shielded sensor cable.
