Ultrasonic Anemometer 4-20mA

The CV7 vane anemometer is an ultrasonic anemometer made in France. This anemometer has proven itself in marine applications, and is renowned for its robustness in the naval sector but also for its accuracy in the competitive sailing sector. 

The sonic wind sensors are static wind vanes, without rotating parts. Thus, the CV7 anemometer is discreet due to its small size and the absence of moving parts that do not attract the eye.

4-20 mA analog output

The SONIC-ANEMO-420-AC is the static ultrasonic wind vane-anemometer, mounted on a vertical arm. This sonic sensor is programmable for dry contact management with alarm triggering wind speed and alarm termination hysteresis. The configuration is stored in a non-volatile EEPROM memory.

Possibility of manual triggering of the alarm. 

Galvanic isolation :

• between the 24 V supply and the sensor supply
• of each loop
• of each dry contact 

The set includes a sensor, 25 meters of cable and the conversion interface. 

Made in France

The CV7 vane anemometers are manufactured in France in the Nantes region, allowing a fast and efficient after sales service. This proximity also allows the manufacturer to adapt these products to your specific needs, do not hesitate to contact us for that. 

The anemometers are subject to drastic quality controls throughout the manufacturing process.
