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

Fellbach, Baden-Wurttemberg (realtimepressrelease) 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 (realtimepressrelease) 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.

Lufft wins innovation award of Baden-Württemberg

Fellbach, Baden-Wurttemberg (realtimepressrelease) November 17, 2015 – The measurement and control technology company Lufft was selected as one winner of the “Dr. Rudolf Eberle Prize” at “Haus der Wirtschaft” in Stuttgart. The award includes prize money of 10.000 Euros. With the innovation of its new mobile road sensor MARWIS, the company from Fellbach triumphed over a field of 77 competitors. Peter Hofelich, the state secretary of the Ministry of Finance in Baden-Wurttemberg, presented the prize to Lufft managing directors Klaus Hirzel and Axel Schmitz-Hubsch. Since 1985, the Baden-Wurttemberg innovation award has celebrated medium-sized companies in the region who have developed outstanding technological innovations in the fields of industry, trade, and technological services.

At the prize ceremony, Lufft manager Klaus Hirzel explained: “Being inaugurated into the line of exceptional and creative developers in this state with this award fills us all with pride. The MARWIS sensor is a result of exceptional engineering expertise and a business plan focused on innovation rather than turnover. In doing so, we followed our credo: global thinking, advanced development, punctual and error-free availability.” Lufft is going to invest the prize money in the research and development of innovative future projects.

The innovative road sensor MARWIS impressed the 12 members of the expert jury, who are elected by the Ministry of Finance from the fields of business and technology. The mobile sensor was introduced in 2014 and is a road weather information sensor that detects road conditions and environmental data reliably. Installed on vehicles, MARWIS records data in real time and straight from the car.

Besides road surfaces (dry, humid, frozen, snow-capped and critically or chemically wet), the sensor records data such as road surface temperature, water film height, dew point temperature, ice friction, and humidity. In doing so, the sensor increases road safety, offers evidence in the case of traffic accidents, aids route planning, and enhances the efficiency of winter service.

Latter will be investigated more precisely. The wholly Lufft owned subsidiary MICKS MSR GmbH which is specialized on meteorological all-in-one systems in the field of transport, received the order to be part of a leading-edge project of the Federal Highway Research Institute (BASt). The order serves the research and development of a distance-based prediction of slippery roads and thus the advancement of the winter road maintenance. In the course of this, the award-winning MARWIS sensor goes into action for the qualification of the data models. More information about the digital test field at the A9 at: http://bit.ly/1MrVa4q.
