Anemometer sensor CV7SF2

wind vanefor boatsultrasonic

Wireless ultrasonic wind vane-anemometer. This version is optimal for installations where cable routing is difficult. The CV7SF2 wireless wind sensor features a 16Hz wind measurement frequency, which enables data refresh at 1 Hz frequency. It is equipped with an interchangeable, latest generation technology LiFePo4 battery that withstands a large amount of charge/discharge cycles and tolerates high temperatures. The radio protocol used has been widely tried and tested since 2013 on our previous versions. The 433 MHz transmission frequency provides a very good radio range and very good protection against interference. No peering system required.
