Non Invasive Road Sensor NIRS31-UMB




Non invasive road sensor with optical principle

Supplementary description:

Measurement of surface conditions such as wetness, ice, snow, or frost; measurement of water film height; measurement of ice percentage in water and determination of freeze temperature; measurement of friction; fully integrated surface temperature measurement (pyrometer) as option; electric isolation of RS485 interface for network with other UMB sensors; easy to mount; firmware-updates via UMB-technology

Special features:

  • UMB-Config-Tool Software for:
  • Configuration of sensors
  • Onsite calibration
  • Real-time date of sensor
  • Firmware-Update for UMB sensors
  • Analoge outputs in combination with 8160.UDAC
