The automatic weather stations comprising GEONICA’s SAFE TUNNEL system are installed at the entrance of the tunnels and have specific sensors for the measurement and monitoring of the environmental conditions inside the tunnels.

The SAFE TUNNEL system has two basic components:
  1. Outdoor Automatic Weather Stations
  2. Sensors Inside the Tunnel:
  • Visibility (EXCO)
  • Combined Optical Sensors (Visibility + Gases)
  • Tunnel Entrance Photometer
  • Illuminance Photometer
  • Gases
  • Air Flux
