Application

• An intelligent sensor which is part of the pole or part of bridge surpassing the motorway.
• Mainly on bridges, which do not allow in all cases embedded sensors
• The NIRS31-UMB is an alternative to Luffts IRS31-UMB.
• Microclimates that need frequent asphalt reconstruction prefer non-invasive technology as well to reduce the maintenance costs.

Features

• Fully integrated surface temperature measurement (pyrometer)
• Electric Isolation of RS485 interface for network with other UMB sensors
• Integrated microprocessors to identify all road and runway conditions.
• Easy to mount - Firmware updates via UMB technology
