The Texas Electronics, Inc. TD-4 Wind Direction Sensor Light Duty is a mechanical style wind meter that measures the horizontal wind azimuth. This unit combines small physical size with superior bearings to meet the EPA's Prevention of Significant Deterioration (PSD) starting threshold requirements. It is a freestanding device for measuring the direction of wind. The sensor consists of a vane and counterweight assembly, which is mechanically coupled to a potentiometer (variable resistor). As the vane rotates in the wind, the potentiometer changes resistance proportionally to the direction of wind.

The recently updated mounting bar, bracket and hardware are included. This allows for the sensor to be simply and easily mounted on a 1" NPT pipe.
