Reinforced heating: The new VENTUS-X from Lufft for extreme locations

Fellbach, Baden-Wurttemberg (allusatoday) August 30, 2017 – Summer is drawing to an end and the cold season is approaching. Reason enough for the Lufft sensor company to introduce an upgraded version of the VENTUS ultrasonic wind sensor – the VENTUS-X. The revised sensor is equipped with an enhanced 240-watt heater and is available from now on.

To get it ready for the market, Avinor, the Norwegian airport integrator, put the VENTUS-X to the test last winter. For the project, they installed two units at two different extreme locations in Norway. A sensor was mounted on Kjølen Mountain, near Tromsø airport, at an altitude of around 2600 feet. Here, the average temperature in winter is minus 23 degrees Fahrenheit. The second was placed on an 1100 feet high summit of Rustadfjell Mountain, near Bardufoss airport, with an average temperature of minus 14 degrees Fahrenheit in January.

Both locations are always very windy and are also exposed to frequent snow showers in the winter. In spite of the adverse conditions, the two VENTUS-X models have delivered reliable wind data since their installation in the autumn of 2016. Sander Bjørn Hansen, system manager at Avinor says: “The new sensors are much improved and [their] stability is now as good as our users could wish.”

VENTUS-X AREAS OF APPLICATION

The robust and maintenance-free wind sensor is particularly suitable for professional meteorological applications in all climate zones. In addition to applications at airports, it can be used particularly well by weather services, at ports, on ships, wind power plants, in traffic management systems, in avalanche and flood warning systems or as a component in other hydro-meteorological monitoring networks.

The robust aluminum housing of the sensor, which is also used for ship propellers, protects against wear and rust. Even salty and humid air, as it occurs in coastal regions, cannot harm the VENTUS-X. Its stability and maintenance-free operation is due not only to the enclosed housing, but also to its advanced measurement principle.

PARAMETERS AND PRINCIPLE OF THE VENTUS-X

The VENTUS-X measures air density, wind speed, wind direction, virtual temperature, as well as air pressure and delivers the data in real time. Wind measurement is based on ultrasonic technology. Using a time-difference method, it is able to determine wind speed and wind direction. It records minimum and maximum values and reports them both in scalar and vector form.

The data is issued via serial and analog interfaces to provide compatibility with as many standard data loggers and PLC (Programmable logic controller) Systems as possible. Available interfaces are SDI-12 and RS-485. The sensor provides the data via the UMB-binary, UMB-ASCII, NMEA, SDI-12, Modbus, and RTU protocols.

An integrated heater keeps the sensor head free of ice even in extreme cold conditions. Additionally, the ultrasonic probes are individually heated to best protect what is most important for the measurement.

MADE IN GERMANY: TESTED AND CERTIFIED

The ultrasonic wind sensors from Lufft have also been tested and certified by official institutions such as TÜV SÜD. They were exposed to extreme temperature, humidity, vibration, and wind. They also successfully tested the ultrasonic wind sensor for electromagnetic compatibility as well as for susceptibility to rust using salt air.

Lufft Launches Vs20k Sensor To Measure Visibility Up To 20 Km

Fellbach, Baden-Wurttemberg (allusatoday) May 5, 2017 – Measurement technology manufacturer Lufft announced the official launch of the VS20k. This is the first Lufft visibility sensor on the market that can measure at distances of up to 20 kilometers, thus making it particularly suitable for meteorological applications or airport monitoring. It’s an addition to the Lufft VS2k visibility sensor with a range of two km.

The right technology to measure reduced visibility

Air saturated with water particles, fine dust, or sand can lead to reduced visibility – a risk factor that all too frequently leads to road and air traffic accidents. Between 2011 and 2015, there were 3,277 accidents on German highways, with 107 of the 3,686 people injured killed.

Lufft’s VS2k and VS20k sensors ensure greater safety on the roads and warn of emergent poor visibility conditions. Both sensors detect visibility at ranges of up to two or 20 kilometers respectively by using measuring reflectance in accordance with the 45° forward scattering principle and deliver updated results every minute. A maximum reading means that the visibility is clear.

Applications, technical details, and advantages of the new visibility sensor

Since meteorological services and airports require reliable sensors with a particularly large measuring range, Lufft has created the VS20k visibility sensor with a measurement range of up to 20 km. It complements theVS2k sensor which measures up to two km. The two sensors are based on the same measuring technique and only differ in terms of certain hardware components and the firmware.

Both the VS2k and the VS20k are low-maintenance. This is due to the anodized and seawater-resistant housing offering IP66-class protection. An intelligent self-monitoring function detects and reports dirt on the lens. The electronics’ automatic zero-point calibration also helps to reduce maintenance intervals. Lufft offers a suitable calibration kit for further on-site calibration measures.

The Lufft UMB visibility sensors can connect with the measurement network via RS485 half-duplex 2-wire and SDI-12 interface.

Vibration for active spider defense

In previous visibility sensor models, spider nests repeatedly affected the accuracy of measurements, resulting in extensive maintenance requirements. This is now a thing of the past thanks to a vibrating motor, a special coating on the unit housing, as well as interference detection.

At a glance: VS2k and VS20k visibility sensors

– 10 to 2,000 or 10 to 20,000 meters measuring range

– Forward scattering method

– Zero-point calibration of the electronics

– Active spider defense

Lufft Introduces New Non-Invasive Road Weather Sensor For Smart Traffic Applications

Fellbach, Baden-Wurttemberg (allusatoday) April 12, 2017 – After a year of development work, a new generation of Lufft stationary street weather sensors is now ready. The StaRWIS, which is installed at a measuring distance of 5.5 meters above the road, is based on an award-winning and innovative LED technology. This is already used with the MARWIS mobile sensor. After introducing the first non-contact road sensor NIRS31 in 2011, the company is now consistently continuing the development of this technology.

SUITABLE FOR TRAFFIC MANAGEMENT APPLICATIONS IN CITIES AND ON BRIDGES

The easy-to-install and compact StaRWIS is a new stationary sensor for road weather information systems. This is based on a non-invasive, spectroscopic measuring principle. The sensor is particularly suitable for hard-to-reach or critical locations, which make installation on the ground difficult or impossible. This includes, for example, bridges or city streets.

StaRWIS provides the values ​​of road temperature, dew point temperature, water film height, road conditions (dry, wet, ice, snow, critical and chemically wet), relative humidity, the percentage of ice and friction. In November 2017, a firmware update will expand the capabilities to include the freezing point temperature and dew point density.

StaRWIS can be installed at a height between five and six meters. Thus, it has a shorter range than the road weather sensor NIRS31-UMB, which can be installed flexibly at distances to the surface of 15 to 50 meters. The innovation therefore complements the portfolio of the Lufft sensors for winter services, smart cities and traffic management applications with a more cost-effective and compact model.

NO COMPROMISES ON ACCURACY, THANKS TO MARWIS LED TECHNOLOGY

The new StaRWIS road weather sensor is based on the same Lufft LED technology as the MARWIS mobile sensor. In this way, it achieves the highest precision that opto-electronic weather sensors are capable of attaining. Like the MARWIS, Bluetooth can be used to wirelessly control the configuration as well as the data transfer. Alternatively, a connection via RS485 and CAN bus is also possible.

“StaRWIS provides all measurements accurately and reliably. It even exceeded our expectations,” reported the first Canadian tester.

Lufft introduces new visibility sensor VS2k and launches MARWIS 2.0

Fellbach, Baden-Wurttemberg (allusatoday) April 26, 2016 – Two innovations are to supplement the product portfolio of G. Lufft, the sensor manufacturer based at Fellbach. The new VS2k-UMB visibility sensor will replace the VS20-UMB optical sensor from the middle of May. The Lufft-UMB VS2k is the first product of an entire series in this segment. The award-winning technology among the Lufft sensors, the MARWIS mobile road sensor, is getting a useful update. The second generation of the sensor replaces its predecessor from now on.

Best tuned to its environment: the new VS2k-UMB visibility sensor

Lufft’s visibility sensor VS2k-UMB is another optical sensor now marketed. In the traffic sector, it serves as equipment for road weather stations and traffic control systems. The sensor measures accurate visibility values in a range of up to 2,000 meters. The VS2k-UMB model replaces the VS20-UMB, which has been used around the world for 10 years. Thanks to intensive development work, the VS2k-UMB visibility sensor features enhanced product characteristics such as a highly optimized housing alloy that is seawater resistant and therefore suitable for offshore use. During numerous saltwater tests, the sensor showed stable longevity even under the most extreme conditions.

The new housing design reduces maintenance frequency significantly, not least by active spider defense. A motor that vibrates within the housing at irregular intervals prevents the arachnids from nestling, which would be a source of interference. In addition, the VS2k visibility sensor has been equipped with further sensors that detect contamination on the optics. Also, the calibration concept has been largely improved. An optionally available calibration disk can be easily attached with magnets and an anchoring to the sensor with little effort.

The new VS2k-UMB visibility sensor is the first product of an entire series that is currently being launched by the sensor company. Another device version with a maximum range of 25 kilometers will be available by mid-year.

MARWIS 2.0 measures air temperature and relative humidity

The mobile road sensor MARWIS, which was among those that were awarded the Industry Prize 2015, measures additional environmental data. The new MARWIS 2.0 version has been equipped with an external temperature sensor which detects the air temperature. With the aid of the other measured variables, this allows the relative humidity to be determined. Until now, the road sensor could measure variables such as the road surface temperature, water film thickness, dew point or road conditions.

Directly attached to the vehicle, the smart sensor transmits the data 100 times per second via Bluetooth in real time to a tablet, smart phone, or an alternative output device in the cab. By using a data cloud, MARWIS can forward the app measurements to the control center, where operations managers can track the test runs using the View Mondo management software.

This version update was launched after requests by many customers. In addition to the road conditions, weather-related data such as the temperature and relative humidity also play a role in evaluating critical conditions such as ice, snow, and hydroplaning. The addition of these two fair values to the road sensor was thus a logical and above all, a practically oriented extension. MARWIS 2.0 will now replace the current model.
