Tunnel Sensors

Solutions for tunnel safety

As the density of the traffic on our roads increases, it is becoming absolutely vital to measure pollutant concentrations in tunnels on a continuous basis. SICK's tunnel sensors measure exhaust gases at source, thereby enabling effective monitoring and control of emissions, and ensuring that ventilation systems operate efficiently – even in the event of a fire.
