Diehl Aviation's product portfolio of Aviation Smoke Detectors is based on the well-proven optical light dispersion caused by fire aerosols. Its multisensory-technology comprises as well a temperature sensor. A sensor chamber heating serves as condensation prevention. As a consequence, our sensors are the most reliable false alarm free smoke detection systems as well for inaccessible areas of the aircraft which also feature a low weight and low electric power consumption. The control can be done via CAN-bus interface.
