Model TD-104-5D Wind Direction Sensor
DESCRIPTION
The Texas Electronics, Inc. TD-104-5D Wind Direction Sensor is a mechanical style wind meter that measures
the horizontal wind azimuth. The sensor is intended for general long-term maintenance free operation.
The TD-104-5D Wind Direction Sensor 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.
