TunnelTech 101

Visibility Monitor

The TunnelTech 101 Visibility Monitor (VIS) is an essential part of any road or rail tunnel safety system.

Overview

The TunnelTech 101 Visibility Monitor (VIS) is an essential part of any road or rail tunnel safety system. Firstly, it monitors the visibility within the tunnel and ensures that the tunnel ventilation system provides sufficient clean air for drivers to clearly see the road ahead.

 

Secondly, used in combination with other TunnelTech 101 VIS monitors, the operator can quickly detect the focus of the fire if it is also equipped with the optional PT100 temperature sensor to accurately measure ambient air temperature in a range of -15 to 105°C.
