Intelligent Passive Road Sensor IRS31Pro-UMB
With 50 m cable
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, and CaCl), road condition (dry/damp/wet/ice or snow/residual salt/freezing rain), friction (Grip), and ice percentage. Optional: 2 additional depth temperatures, e.g. at 5 cm and 30 cm. The sensors are addressable and can be networked. The measurement data is available for further processing in the form of a standard protocol (Lufft UMB protocol).
Freezing temperature output already from pre-set dry-damp threshold (e.g. 10 µm according to new TLS specification).
Replaceable sensor electronics
Polling via RS485 interface
Low energy consumption (solar operation)
Radar principle to measure water film
Analogue outputs in combination with 8160.UDAC
