smart/AQM Smart IoT Air Quality Monitor
smart/AQM measures the visibility in a tunnel with scattered light and up to 3 gases with electrochemical sensors
smart/ECS Smart IoT Multi Gas Sensor
smart/ECS measures toxic gases in tunnels and other underground structures
t/LUM Luminance meter
t/LUM measures the luminance in the access zone in front of the tunnel as well as in the threshold and interior zone inside the tunnel
t/FL-US Air flow monitoring system - Ultrasonic cross-section
t/FL-US precisely and reliably measures the average longitudinal air velocity over the entire tunnel cross-section
t/FL-DP Air flow monitoring system - Differential pressure
t/FL-DP measures the longitudinal air velocity with differential pressure at 2 points in the tunnel cross-section
t/LUX Illuminance meter
t/LUX measures the illuminance in and in front of a tunnel
t/DIM-A Amplitudenregler
t/DIM-A dimmt stufenlos Tunnelleuchten zur Optimierung der Leuchtdichten bei gleichzeitiger Energieeinsparung
t/SIG Traffic signal controller
t/SIG controls and monitors the light sources of traffic light signalling devices
t/EXT Extractive visibility and gas monitoring system
t/EXT measures visibility and CO concentration outside the driving area and guarantees maximum availability of the tunnel
t/VIS-TR Visibility sensor - Transmission
t/VIS-TR measures the visibility in the tunnel by means of light attenuation along a measurement path (transmission)
