Technical Data Intelligent Passive Road 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... 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 Article number 8910.U050, 8910.U051, 8910.U052, 8910.U100, 8910.U101, 8910.U102 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, Page 1 Technical modifications and errors excepted - Created 03/03/2021 G.
