This compact vane anemometer is for use on large vessels. It sends both wind direction and speed signals simultaneously from the transmitter for remote observation.
The transmitter is a propeller type and is used in combination with the wind speed/direction indicator. It displays wind speed and direction by using a patented internal optical pulse system. It is highly durable and accurate. Constructed of lightweight, strong polycarbonate, this wind speed and direction instrument uses optical fiber instead of a traditional spring mechanism for wind measurements, and the wind direction finder employs an 8-bit encoder.
Key Features Include:
Compact and lightweight
Two piece system – vane transmitter & digital indicator
Easy to read analog and digital displays – separate indicator display systems
Digital readout of average wind speed
Reading in meters per second (m/s) or knots
Digital updates every 10 minutes of average wind speed
LED analog display for momentary change in wind direction and speed
Includes both wind speed and wind direction sensors
