Detailed description

Designed for high-performance marine integration, the LCJ CV7 ultrasonic wind transducer / vane anemometer NMEA 2000 combined with the WINDYPLUG NMEA 2000 interface provides a solution for measuring wind and atmospheric data. The CV7 sensor uses ultrasonic technology, eliminating moving parts and reducing wear for long-term reliability.

CV7 Sensor Performance and Accuracy

The CV7 sensor delivers precise measurement of wind speed and direction. It has a wind sensitivity starting at 0.12 m/s (0.25 knots) with a resolution of 0.05 m/s (0.1 knots) and a dynamic range from 0.12 to 40 m/s (0.25 to 80 knots). Wind direction is measured with a sensitivity of +/- 1.5° and a resolution of 1°. Data refresh rate is 2 Hz, with internal measurements at 30 Hz. The sensor operates on 8 to 30 V DC power and consumes 9 mA. It is designed to function within a temperature range of -15°C (excluding icing) to +55°C. Its 310 mm angled aluminum arm (Ø12 mm) facilitates installation at masthead.

WINDYPLUG NMEA 2000 Integration

The WINDYPLUG NMEA 2000 interface enables direct connection of the CV7 sensor to your NMEA 2000 network. This adapter includes a barometric sensor. It transmits atmospheric pressure data (range 850 hPa to 1150 hPa) with a resolution of 1 hPa over NMEA 2000 V2. Relative accuracy is +/- 0.5 hPa at 20°C, and absolute accuracy is +/- 1.5 hPa at 20°C. The WINDYPLUG is powered via the NMEA 2000 network (8 V to 28 V DC) with a consumption of 1 LEN (< 40 mA with sensor) and features IP66 protection once connected. It weighs 35 g and measures 81 mm in length with a 17.5 mm diameter.

Features and Certifications

The system is CE, EN 55022, and EN 55024 certified, confirming compliance with European standards. The setup is configurable for wind angle adjustment, offering adaptability to user preferences. French manufacturing by LCJ Capteurs ensures quality control and a design focused on durability in marine environments.

Expert opinion

« Technical analysis of LCJ CV7 and WINDYPLUG: Ultrasonic robustness and NMEA 2000 integration »

The LCJ CV7 sensor with the WINDYPLUG NMEA 2000 interface represents a robust technical solution for measuring wind and pressure parameters aboard. The CV7 sensor's key advantage lies in its ultrasonic design, which eliminates all moving mechanical parts. This feature is critical in marine environments, where constant exposure to elements (salt, UV, vibrations) inevitably degrades traditional cup and vane anemometer systems. The absence of maintenance and long-term measurement stability are decisive arguments for demanding sailors.

The WINDYPLUG interface is the highlight of the system integration. It converts the NMEA 0183 signal from the CV7 into a NMEA 2000 stream, making it compatible with nearly all modern electronic networks. The integration of a barometric sensor directly into the WINDYPLUG is a functional advantage, as it centralizes a key meteorological data point without requiring an additional sensor. Installation is simplified by its Micro C male connectors, allowing direct connection to the NMEA 2000 bus. For masthead installation, the CV7's angled arm is well-designed to coexist with other equipment (VHF antennas, navigation lights).

This system is suitable for measuring wind and pressure parameters in marine applications. The robustness and French manufacturing of LCJ Capteurs are marks of quality. While initial setup requires careful alignment, the adjustment options offer great flexibility to adapt the sensor to the specific needs of each vessel. It is a relevant choice for those seeking a reliable, precise, and low-power solution for marine instrumentation.
