MODEL TV- 4 WIND SPEED SENSOR
DESCRIPTION:
The Texas Electronics, Inc. TV-4 Wind Speed Sensor is a mechanical style anemometer that measures the
horizontal velocity of wind. This unit combines small physical size with superior bearings to meet the EPA's
Prevention of Significant Deterioration (PSD) starting threshold requirements. The TV-4 wind speed sensor is a
freestanding device for measuring air velocity. The sensor consists of a lightweight 3-cup anemometer, which
electromechanically converts wind speed into a measurable electronic signal.
The output signal can be presented in 3 optional forms: a pulsed DC signal, an AC frequency, or a conditioned
analog signal. Each output has a specific application. The pulsed DC signal is used where high-accuracy is needed
and continuous power is not a problem. The AC frequency output is used in situations where power consumption is
critical. And finally, the conditioned analog signal is used to easily and quickly communicate with virtually all
digital control systems such as PLC's or SCADA systems.
