TV-4 Wind Speed Sensor Light Duty


TV-4 Wind Speed, Light

SKU: 920-00003 Categories: ,

The Texas Electronics, Inc. TV-4 Wind Speed Sensor Light Duty 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 required and continuous power is not an issue. 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.

The recently updated mounting bar, bracket and hardware are included.
