Cost effective and longer lasting wind sensing technology


Over 20 years, LCJ Capteurs has been designing and manufacturing ultrasonic wind vane - anemometers. As the forerunners of the ultrasonic wind sensor in the marine sector, this French company offers products that are very good value for money with self-sufficient energy thanks to its wireless capability.


The product range has been improved and enhanced to offer the best and most efficient compact, robust and lightweight wind sensors. These are designed and manufactured in LCJ’s workshop, but also tested in wind tunnel, climatic chamber and ageing bench. Every test is recorded against the unit’s serial number to ensure reliability, accuracy and robustness.


High Quality Wind Measurement Solutions


OEM version available


Thanks to ultrasonic technology, there are no rotating parts on the LCJ Capteurs’ products. This is why these sensors have a much longer life span than conventional wind vane anemometers.


Three types of terrestrial sensors are available: NMEA 0183, Modbus – analogue, ultra-low/zero-power. Sensors already mounted on vertical poles (external power supply or self-powered) or OEM solutions to incorporate into bespoke systems are available, as well as tailor-made finished products. These solutions are compatible with all interfaces used on weather stations.


The LCJ Capteurs’ ultrasonic wind sensors are supplied to weather station integrators, connected agriculture systems, smart buildings, the sports sector, pollution detection systems and various other domains.


As the company continues to grow, extension works on their headquarters have been carried out in order to increase the production and storage capacity to meet the steady increase in demand.

Rain and precipitation measurement made easy, wherever and whenever its needed

The RHD sensor from Sommer is a competitively priced, high precision, ultra-robust rain gauge instrument. It is a very low-power, maintenance- free and totally sealed acoustic instrument with no mobile parts. The sensing part of the instrument is a polished stainless-steel hemisphere supported by a strong stainless-steel arm.


Impact of raindrops or hailstones induces change in internal acoustic pressure. In addition to the rain intensity data, the distrometer function also provides information about the drop size distribution. If you need a solution for remote or tough to access areas and you do not have the manpower for regular checking/maintenance of your rain gauge then this is the perfect choice of sensor. It is also available as a “plug and play” station which includes data storage, data processing installation tools and enough power solution to be an autonomous station.


The instrument includes a dedicated analogue conditioning module, a digital I/O module and an analogue restitution module. It can therefore be connected to, or communicate conveniently with, almost any external analogue or digital central unit (data logger, industrial module interface, instrumentation DAQ, USB port). It features continuous or pulse analogue voltage outputs and supports SDI-12 communication, serial RS-232, and Modbus RTU RS485 (using an optional adapter).

Engineered in the UK for the demanding accuracy, reliability and durability requirements of the Wind Energy industry, the Vector Instruments range of First Class wind sensors are also suited to many other applications, including industrial, agricultural, transport, aero, marine, military, research and general meteorology. These wind instruments are engineered to perform and built to last.


The Vector Instruments A100L2 and W200P models are the basis of the UK Meteorological Office’s current MK6 wind instrument set, and the A100/W200 instrument family is used in applications worldwide by industry, research and weather agencies. These robust instruments have provided users with good wind data throughout some of the most powerful typhoons & cyclones in recent years.


The high-quality components used to construct these A100/W200 series anemometers and wind vanes yield better wind measurement accuracy, lower power-consumption and higher durability/service-life as compared to many other mechanical/ultrasonic wind sensors on the market. Many years of field experience and optimisation of the design of these traditional/ mechanical “First Class” instruments means that, despite having moving parts, they can still outperform many other wind measurement technologies in general meteorological applications, achieving the required measurement accuracies while needing little or no maintenance for extended periods.


With over 40 years of experience designing and manufacturing wind sensors and on-going development and improvement, these wind instruments are in use worldwide and have a proven track record and long life in the field.

Weather monitoring in extreme conditions


52721pr@reply-direct.com one of the most remote locations on Earth.


Aerosols are important in cloud formation because they act as condensation nuclei, providing seeding sites for water vapour condensation, and as ice nucleating particles which modulate the formation of ice in clouds.


The Greenland Ice Sheet is of critical importance to human society because of its role in global sea-level rise, and is of particular concern because it is melting at an increasing rate. An understanding of aerosol-cloud interactions is therefore extremely important; especially where clouds are comprised of both ice and supercooled liquid water, because this represents a major source of uncertainty in weather and climate models. Scientists from the University of Leeds School of Earth and Environment, and the National Centre for Atmospheric Science are therefore seeking to reduce this uncertainty with the use of advanced remote sensing technology, such as radar and lidar, in combination with satellite observations and a suite of other ground-based sensors (such as the Ventus) and state-of- the-art numerical weather and climate models.


The project is seeking to determine the extent to which different aerosol properties cause significant changes in clouds, and to quantify the role aerosols may have on the melting of the Greenland Ice Sheet. In addition, this work is evaluating regional and global numerical weather and climate model performance against the project’s observations; to identify any deficiencies that lead to biases in cloud occurrence, cloud thickness, and phase partitioning.

A Ventus X ultrasonic wind sensor, manufactured by OTT HydroMet has been deployed by researchers at the Summit Station on the Greenland Ice Sheet in the Arctic, 10,000 feet above sea level, as part of a project investigating the role of aerosols in cloud formation. With integrated heaters and no moving parts, the wind sensor does not require recalibration – a vital feature of equipment in
