Wind Speed & Direction
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 instructionmanual.
