Runway weather sensor IRS31Pro-UMB

The passive road sensor IRS31Pro-UMB convinces by its two part housing design and accurate detection of road surface temperature, water film height, freezing temperature, ice percentage and many more... The passive road sensor IRS31Pro-UMB is flush-mounted in the road. The two part housing design allows the combined sensor/electronics unit to be removed for maintenance or calibration at any time. The following variables are recorded: Road surface temperature, water film height up to 4 mm, freezing temperature for different de-icing materials (NaCl, MgCl, CaCl), road condition (dry/damp/wet/ice or snow, damp with salt, wet with salt), friction (Grip), ice percentage. Optional: 2 additional depth temperatures, e.g. at 5 cm and 30 cm. The measurement data is available for further processing in the form of a standard protocol (Lufft UMB protocol). Parameters measured:Road surface temperature, water film height up to 4mm, freezing temperature for different de-icing materials (NaCl, MgCl, CaCl), road condition (dry/damp/wet/ice or snow/moist with salt/wet with salt), friction, ice Percentage, 2 additional depth sensors Measurement technology:Conductivity measurement (ice percentage), radar measurement (water film), NTC (road surface temp.) Product highlights:Two part housing design allows easy maintenance/re-calibration, low energy consumption allows solar operation, radar principle to measure water film Interfaces:RS485, SDI-12, analogue outputs Freezing temperature output already from pre-set dry-damp threshold (e.g. 10µm according to new TLS specification). Replaceable sensor electronics (for easy calibration or maintenance) Polling via RS485 interface
