KOSHIN Marine Vanes (Anemometer) 〈FV-301A〉
An anemometer is an equipment which measures both wind speed and wind direction, simultaneously. This equipment shows on display the relative direction and relative speed of wind flowing above a travelling vessel. It can be used on a wide variety of vessels – small boats, fishing boats, and work ships.
Marine Vane FV-301A
In pursuing the highest achievements in design and function, Tamaya has engineered a more compact and lightweight anemometer.
A new compact design (2/3 smaller and 1/5 the weight of recent models), and improved function through a patented internal optical pulse system, make this wind speed and direction instrument more durable and accurate than ever before.
In anemometers, the essential choice is the Marine Vane FV-301A.
-The transmitter housing is made of plastic, reducing weight by 1/5 and overall area by 2/3 which allows for easy installation.
2.High Durability Propeller
-Wind speed detecting propeller is made of highly durable, lightweight glass fiber polycarbonate.
3.Increased Accuracy Through Optical Technology
-Patented non-contact system for wind measurement uses optical fiber instead of the traditional spring mechanism and the wind direction detector employs an 8-bit encoder. Both features provide increased reliability and accuracy.
4.Easy-to-read Analog and Digital Displays
-Separate display systems in indicator provide a digital read-out of average wind speed and an analog(LED) display for instantaneous wind direction and speed.
5.Unit of wind speed can be switched between m/s and knot
6.Digital display updates avarage wind speed every 10 minutes
7.Digital illumination can be adjusted by remote control for night voyages (Optional)
