TV-110-L320, Wind Speed Optical, Medium

The Texas Electronics, Inc. TV-110-L320 Wind Speed Sensor is a mechanical style anemometer that measures the horizontal velocity of wind. This unit is designed to meet or exceed all the EPA's Prevention of Significant Deterioration (PSD) requirements.


The TV-110-L320 wind speed sensor is a freestanding device for measuring air velocity. The sensor consists of a lightweight 3-cup anemometer, which is mechanically coupled to a 20-slot disc located within the sensor housing. A light beam, produced by an infrared light emitting diode (LED), passes through the slotted disc and falls upon a light-detecting transistor. The transistor switches on and off 20 times for each revolution of the cup assembly. Therefore a pulsed output is produced which is proportional to wind speed.
