Description

LCJ CV3F ultrasonic wind sensor

LCJ CV3F is an ultrasonic wind sensor for marine and professional installations where reliable wind speed and direction data are required without a conventional rotating cup or vane mechanism. Correct performance depends on more than the sensor itself: mounting position, clear airflow, power supply, cable routing and the receiving instrument all need to be considered together. F&C Marine can help confirm the CV3F configuration and installation requirements before supply.

Ultrasonic wind measurement

Ultrasonic wind sensors measure airflow electronically rather than relying on moving mechanical parts. This can simplify maintenance and removes the bearings and rotating elements found on traditional anemometers, but installation position remains critical. Any obstruction close to the sensor can disturb the airflow and introduce errors. The sensor should therefore be positioned where rigging, masts, aerials, exhausts and other structures have the least practical influence on the wind reaching the measuring area.

Mounting and site selection

Before fitting the sensor, inspect the proposed mounting point and cable route. The mounting should be rigid, correctly aligned and accessible enough for future inspection. If the CV3F is replacing an older wind instrument, do not assume that the previous mounting position is automatically ideal. Review nearby structures and any changes that may have been made to the vessel or site. The LCJ range also includes mounting adaptors, so identify the existing thread or bracket arrangement before ordering accessories.

Power and data integration

The wind sensor is only useful when its data can be received correctly by the rest of the installation. Identify the display, instrument, logger or navigation system that will use the wind information and confirm the interface before ordering. Check the available power supply, cable length and route, and protect the wiring from water, heat, sharp edges and unnecessary electrical interference. On a refit, label existing conductors and photograph connections before removing the old equipment so the new installation can be commissioned systematically.

Commissioning and wind-data checks

After installation, verify that the receiving equipment shows plausible wind speed and direction and that the orientation of the sensor is correct. Compare the displayed direction with the physical installation and check for obvious errors caused by alignment. Where possible, observe the readings under different headings or wind conditions. If the wind data is distributed to more than one bridge device, confirm the values at each destination. Record the final sensor model, orientation, cable route and interface for future fault finding.

Maintenance and fault finding

Although an ultrasonic sensor has no conventional rotating cups or vane, the installation still benefits from routine inspection. Check the sensor for contamination, physical damage and secure mounting, and inspect exposed cable and connectors for deterioration. If wind data becomes intermittent or implausible, check power, wiring, data interface and receiving equipment before assuming the sensor has failed. A network or supply fault can create symptoms that look like a wind-sensor problem.

Documentation and related guidance

For manufacturer information, see LCJ Capteurs products and the LCJ support and download area. Manufacturer documentation should be used as the final reference for wiring, mounting, interfaces and configuration. You can also read F&C Marine’s ultrasonic vs mechanical wind-sensor guide and use the Marine Electronics Knowledge Base.

Before ordering LCJ CV3F

Send F&C Marine the vessel or site type, existing wind instrument details, photographs of the proposed mounting position, cable-route information, supply voltage and the make and model of the equipment that needs to receive wind data. If this is a fault replacement, include the symptoms and tests already completed. We can then help confirm whether LCJ CV3F is the right sensor and identify the interface, mounting and installation requirements before a quotation is finalised.
