advanced Road/Runway Surface ICE Detection Sensors/Ceilometer's/ Met Sensors

 

High performance intelligent invasive/non- invasive & mobile real time sensors for road/runway surface ice detection, freeze point temperature measurement, water film height & surface grip measurement.

Lufft's UMB (Universal Measurement Bus) technology with open protocol, offers lean modular strategy that will communicate with any 3rd party hardware such as Variable Message Signs (VMS), Traffic Control Centres and OEM system integrators and data loggers.

Measures freeze point temperatures, water film height up to 4mm, & now "friction" (Grip) in addition to other critical surface condition status such as wetness, ice, snow, hoar frost & residual salt. Active sensor measures freeze point temperature independent of de icing material, making it ideal for bridge deck applications where alternatives to sodium chloride are sometimes used to prevent corrosion.

 

Benefits of non invasive road weather sensors:

-Automatic calibration according to surface construction (concrete or asphalt).
-Automatic re calibration during dry periods (surface conditions)
-No need to adjust the unit according to the distance between installation point & surface.

-Can be re positioned easily.

All sensors are configured & firmware updated using the free UMB-Config.net software tool.

See further down this page for actual measurement comparison between embedded road sensor (puck) with non-invasive technology.


New remote data hosting & cloud storage platform-ViewMondo available to put all your winter weather data in one place (fixed & mobile stations).

IRS31Pro-UMB Passive Intelligent Road/Runway Surface Condition Sensor.

Fourth Generation IRS Passive Sensor with improved accuracy

Measures:

- Road surface temperature

- Water film height up to 4 mm

- Calculates Freezing temperature for different de-icing      materials   (NaCl, MgCl, CaCl).

- Reports Road Surface Condition (dry/damp/wet/ice or snow/residual salt/freezing point)

-Friction (Grip)

-Ice percentage.

Optional 1 or 2 deep temperature sensors.

ARS31 Pro-UMB Road/Runway Active Ice Forecast Sensor.

Lufft ARS31Pro-UMB active road/runway sensor measures the freezing temperature of a liquid on the road/runway surface.


Product concentration (potassium acetate, potassium, Cryotech E36, Safeway KF Hot)


Freezing temperature measurement is independent of mixture ( electrical conductivity of the solution must be > 1 mS/cm).

In addition, ARS31Pro-UMB can determine the threat of icing using an external surface temperature sensor connected directly to the ARS31Pro.

NIRS31-UMB Non Invasive road surface condition sensor

Spectroscopic measurement of:

-Surface Condition-Dry, Damp, Wet, Snow, Ice

-Water Film Height/Layer Thickness

-Ice % in water

-Surface Temperature

-Determination Of Freeze Point Temperature

-Grip (Friction).

Lufft StaRWIS Non-Invasive Road Wather Sensor.

MARWIS Mobile Runway Weather Sensor.

Integrate into SnowTam.

Measures winter runway surface grip & water film level at 100Hz.

NEW: Now measures ambient humidity in addition to surface humidity at the runway surface.

 

Reduce winter maintenance costs by intelligent knowledge of the current runway surface condition in real time by applying the deicing chemical only where it is needed, rather than re- treating the full length of the runway.

The new MARWIS low cost intelligent mobile Runway surface weather sensor from lufft reports surface weather data in real time on Runways &Taxiways.

Display data inside vehicles on Tablet devices using the free Lufft MARWIS App &/or transmit data directly to a remote server.

Lufft UMB ( Universal Measurement Bus) Technology

Main Advantage: Open Protocol, not a closed box solution.

Technology for recording environmental data.

The modular system approach supports easy commissioning, free firmware updates & data transfer over RS232, RS485 or GPRS modem.


UMB offers flexibility, modularity.

Analogue sensors can be connects to the UMB BUS simply by using the ANACON modules.

The DACON8  D/A converter module provides 8 channel analogue outputs.
