New UltraSonic Wind Sensor for Motorboats

With Wind Temperature Correction

CV7-V ultrasonic wind sensor

CV7-V ultrasonic wind sensor

VERTOU – France  —  The LCJ Capteurs CV7-V is designed to fit the specific needs of sailing boats, and terrestrial application through an easy to use programmable interface.

As standard, all LCJ Capteurs sensors transmit information of wind measurements by the NMEA0183, RS232/RS422 (0/5 V signal), very easy ASCII, USB, and 4800 baud protocol.

They also offer an UltraSonic Wind Sensor with SDI12, and NMEA2000 interface.

The ultrasonic sound is conveyed by the movement of the wind in which it crosses.

The electro-acoustic CV7 transducers communicate between themselves two by two by ultrasonic signals to measure, following the orthogonal axes, the wave transit time differences induced by the air flow.

The measurements are analysed by integrated calculator in order to establish the wind module and its direction in relation to a reference axis.

Other Actions:

1. Temperature measurements are used for calibration corrections of the head mast ultrasonic wind sensor.

2. CV7 Transducers communicate between themselves delivering four independent measures while head wind measured vectors are preferably used for calculations.

3. The effect of an inclination of the head mast anemometer is partially corrected due to the shape given by the space. This method gives a sensibility of 0.12 m/s (0.25 knots), a dynamic of 40 m/s (80 knots) and an excel

About LCJ Capteurs

LCJ Capteurs has designed and manufactured wind sensors since 1999. Their range of wind vanes/anemometers covers the needs over many applications. Their sensors have proved their robustness and accuracy on the marine sector, and they are now widely used in other fields such as weather stations, industry, security and agriculture, to name a few.
