The Model A70-SD system provides electrical signals proportional to wind speed and direction.It accepts signals from anemometers with AC generators such as the Comptus A75-104.The translator will operate with most potentiometric type wind vanes. The Translator may be in one of several packages. It may be track mounted for installation in an existing enclosure. It may be supplied in a steel NEMA 12 JIC box for inside deployment or in a steel NEMA 4 box when a weather proof box is required.
The transmitter converts the information from the sensors to 4-20 ma signals proportional to wind speed and direction. Systems are available with outputs of 0-1 mA, 0-1 V, 0-5 V, or 4-20 mA. All systems may be powered from either 24 VAC, 120 VAC, 230 VAC, or 12 – 24 VDC.
The instruments are available in a variety of packages including steel JIC boxes meeting NEMA 12 standards, weatherproof fiberglass enclosures meeting NEMA 4X, IP66 and IEC 529 standards and track mounted versions. NEMA 12 enclosures provide protection from dust for indoor applications. NEMA 4X enclosures may be used indoors or outdoors. They provide protection from corrosion, wind blown dust and rain and are undamaged by ice. Track mounted versions are intended for mounting inside an enclosure provided by the user. Where required, electrical connection to the sensor is via terminal block. A barrier strip is provided for connection to operating power.
Each system is provided with a detailed instruction manual.
