Description

LCJ CV7-V ultrasonic wind sensor

LCJ CV7-V is the vertical-masthead version of the CV7 ultrasonic wind sensor, supplied in the listed NMEA 0183 configuration. It is designed for marine installations where wind speed and direction are required without conventional rotating cups or a vane. Correct performance depends on clear airflow, secure vertical mounting, correct orientation, a protected cable route and a compatible receiving instrument. F&C Marine can help confirm the installation before supply.

Ultrasonic wind measurement

The CV7 measures wind electronically and therefore has no conventional cup or vane bearings in the measuring assembly. That can reduce mechanical maintenance, but the sensor still needs a good airflow environment. Nearby aerials, mast fittings, rigging and other structures can disturb the wind around the sensor and affect readings. The mounting point should therefore be selected to minimise local turbulence, and the sensor orientation should be checked carefully against the vessel reference.

Vertical masthead installation

The CV7-V configuration is intended for a vertical masthead arrangement. Before fitting, inspect the available bracket or mounting structure and make sure it is rigid, correctly aligned and suitable for the sensor. If replacing an older wind instrument, do not assume that the existing position or adaptor will automatically suit the CV7-V. Changes to antennas or mast hardware can alter airflow, and a damaged bracket or cable route can remain a problem after a new sensor is installed.

NMEA 0183 and electrical integration

The listed CV7-V version uses NMEA 0183, so the receiving display, instrument, autopilot, logger or navigation system needs to be identified before wiring. Confirm the relevant data input, polarity and configuration at the receiving device. If several devices require wind data, review the complete talker/listener arrangement. Check supply voltage and cable condition as part of the installation, and protect wiring from water, sharp edges, heat and unnecessary electrical interference.

Commissioning and wind-data checks

After installation, verify plausible wind speed and direction at the receiving equipment. Check the physical orientation of the sensor and compare displayed wind direction with the vessel heading and actual conditions. Where wind data is repeated to several bridge systems, confirm the values at each destination. Test the installation while other equipment is operating and investigate intermittent data before handover. Record the model, mounting orientation, cable route and interface for future service.

Maintenance and troubleshooting

Routine checks should include the sensor body, mounting hardware, exposed cable and accessible connections. Look for contamination, damage, corrosion and water ingress. If data becomes intermittent, check power and NMEA 0183 wiring before replacing the sensor. If direction is consistently offset while speed remains plausible, review physical alignment and any configured offset in the receiving equipment. Keeping accurate installation records makes later fault finding considerably easier.

Documentation and related guidance

For manufacturer information, see LCJ Capteurs products and the LCJ support area. Current LCJ documentation should be the final reference for mounting, wiring and NMEA 0183 configuration. F&C Marine also provides an ultrasonic vs mechanical wind-sensor guide and the Marine Electronics Knowledge Base.

Before ordering LCJ CV7-V

Send the vessel type, current wind equipment, photographs of the masthead and mounting, cable-route details, supply information and the make and model of the equipment that will receive wind data. If the unit is replacing a fault, include symptoms and tests already completed. F&C Marine can then help confirm whether the LCJ CV7-V vertical NMEA 0183 version is correct and identify any mounting or interface requirements before quotation.
