-
- IoT-enabled visibility and gas sensor for use in tunnels. The visibility measurement is based on the scattered light principle, the gas measurement is performed with up to 3 electrochemical cells.
-
-
- IoT-enabled gas sensor for electrochemical measurement of gas concentration with up to four gas sensors modules. Specifically designed for application in tunnels.
-
-
- Robust air flow monitoring system based on high-precision differential pressure measurement. Specifically designed for tunnels.
-
-
- Accurate ultrasonic air flow measuring system based on different transition times of ultrasonic pulses. Reliably measures the average air flow over the whole tunnel cross section.
-
-
- Photometer to measure the luminance in the access zone, threshold zone and interior zone of tunnels. Includes a zoom lens to adjust the focus areas.
-
-
- Visibility measuring system according to the transmission principle, specially developed for the requirements in tunnels. The measuring range for the analog signal is freely assignable.
