Recognized by the German Weather Service (DWD) the Lufft CHM 15k has been selected as the ceilometer of choice for their nationwide cloud monitoring network. Lufft ceilometers reliably detect various cloud heights, cloud amount and cloud cover and provide other essential parameters and index that informs the user of the Sky Condition, visibility and aerosol layers.

The ceilometer has a simple to use interface, and it’s designed to be a drop-in upgrade solution to any deployed ceilometer. With its open communication protocol, it can seamlessly be added to any existing ceilometer network.

The resolution is such that the ceilometer is able to detect volcanic ash particles, having a decisive influence on the air traffic. One extreme example was the eruption of the Eyjafjallajökull volcano in Iceland in 2010 paralyzing a huge part of the European air traffic for several days. Having a Lufft ceilometer network would have supported the routing efforts for air traffic personnel.

The Lufft CHM 15k is equipped with a one-wavelength backscatter LIDAR and stands out through its stable wavelengths, immunity against environmental influence factors such as fog, precipitation or temperature extremes and its wide measurement range of 15km.

Moreover it’s precise, rugged, eye-safe (1M classification), user-friendly as well as cooled or heated automatically. The window is kept clean by a window blower.

The CHM 15k works by sending out a laser beam reflected by its sensitive photo receivers creating a backscatter profile. Small bandwidth filters precisely detect cloud heights, aerosol layers and multiple cloud layers.

Fourty-six out of fitfty landing accidents are caused by slippery runway conditions, that is 92% (source: The Boeing Company). To avoid weather-caused landing accidents, runway condition sensors from Lufft inform on several surface status such as temperature, water film height, ice percentage and friction.

There are different types of Lufft runway sensors: embedded ones (IRS31Pro-UMB and ARS31Pro-UMB) and the mobile sensor MARWIS.

The active freezing temperature sensor ARS31Pro-UMB was proven successfully by the BASt following the valid inspection rules of CEN/TS 15518-4:2013. The sensor is flush-mounted in the runway surface and measures the freezing temperature by means of active cooling and heating independently from the de-icing mixture. In addition, it measures the surface temperature. Its two-parted housing design allows the electronics unit to be separated from the casing for maintenance purposes at any time, in just a few minutes.

The latter also applies for the passive embedded road weather sensor IRS31Pro-UMB. Besides the freezing point for NaCl, MgCl and CaCl as well the surface temperature, the IRS31Pro-UMB records water film heights of up to 4mm, road conditions (dry, damp, wet, ice or snow, residual salt, freezing water), ice percentages as well as friction. Optionally, it can be complemented with up to two different depth temperature sensors in 5cm or 30cm depths. They help to predict occurring surface freezing.

At airports the intelligent combination of the passive IRS31Pro-UMB and the active runway sensor ARS31Pro-UMB is necessary to be informative about the de-icing chemical. The ARS31Pro feeds the IRS31Pro with the freezing temperature, with which the de-icing-fluid concentration can be calculated.

With a measurement frequency of 100 times per second, the innovative MARWIS satisfies the requirements of a smooth movable and real time measurement device. The data can be viewed on a free iOS or Android app as well as remotely in the operation centre. This all-in-one sensor covers a big variety of weather parameters that include: Dry, moist, wet, snow, ice, chemically and critically wet, temperatures, dew points, ice percentages, water film heights, relative humidity as well as friction.

Lufft Weather Sensors for Airport Weather Observation Systems

WS3000-UMB Smart Weather Sensor for Measuring of Air Temperature, Relative Humidity and Air Pressure

In 2016 a Lufft introduced an innovative weather sensor family exceeding all previous weather sensors in terms of precision. Measuring very precisely temperature, humidity and air pressure, the WS3000 is an indispensable component of a AWOS system.

The sensor is part of the highly precise weather sensor family WS1000 and is the first multi-parameter sensor which can be dismantled completely. This is extraordinary useful for maintenance and calibration purposes and turns the WS1000 family into a sustainable product line. Through an included WiFi-module, the data can be obtained wirelessly and comfortably. The measurement output can be accessed by the industry standard open protocols.

A second, redundant pressure sensor can be included optionally to comply with any AWOS requirements. In addition we offer the WS3100, which has an additional CMP10 radiation sensor from Kipp&Zonen included.

WS200-UMB to WS800-UMB - Professional All-in-One Weather Sensor Family

Adding to solutions to monitor airspace and runway surface conditions, Lufft has been the first to develop all-in-one ambient weather sensors: The WS Family of sensors come with an open protocol digital interface, embedded aspirator and a weather-proof cable. The series ranges from a sensor that only measures wind to a model with eight integrated sensors to measure lighting, solar radiation, precipitation, wind, temperature, humidity, and pressure in one casing connected with one cable reducing installation, integration and maintenance time.

VENTUS-UMB for Very Precise Measurement of Wind Speed and Wind Direction.

The VENTUS-UMB measures extremely precise and maintenance-free wind speed, wind direction and air pressure. Furthermore, the Ventus calculates the acoustic virtual temperature. This ultrasonic wind sensor is designed without mechanical parts traditionally called “cups and vane”, removing the need of yearly recalibration The closed and rugged housing protects from external interference factors, such as birds or hail. All these features make the Lufft Ventus ideal for AWOS applications where reliability and performance is key in extreme environment applications.
