Observator 100 years

IRS31Pro Road Sensor installed on one of the largest terminals in the Netherlands

Monday 19 October 2015

After the detection of the cold spots on the site of the terminal, the first IRS31Pro-UMB Intelligent Passive Road Sensorsare installed. The cold spots were detected by using the Marwis, a mobile road condition sensor (mobile road weather information sensor).

The sensors are used to see if the condition of the road is safe for operating the container carriers. All data is shown on OMC-Data-Online, the Observator data management software package.

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/residual salt/freezing rain)
  • Friction (Grip)
  • Ice Percentage
