MicroStep-MIS
Intelligent Road Surface Condition Sensor IRS31 Pro
Passive road sensor IRS31 Pro 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.

Features

  • Replaceable sensor electronics
  • Polling via RS485 interface
  • Low energy consumption (solar operation)
  • Radar principle to measure water film
  • Analogue outputs
The following variables are recorded:
  • Road surface temperature
  • Water film height up to 4 mm
  • Freezing temperature for maximum 10 ice melting materials
  • Road condition (dry/damp/wet/ice or snow/residual salt/freezing rain)
  • Friction (grip)
  • 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.
