Abstract(s) :

(Anglais) Sochinor together with the Faculté Polytechnique de Mons and Materia Nova (research Centre in Mons) have developed gas sensors based on semiconductors for fire detection in dusty industries. These specific sensors are commercially called Pyros-F. The project consisted in installing an experimental system for fire detection based on Pyros gas sensors in the production plant in CBR Antoing. The detection system consists of groups of detectors strategically placed linked to an Central Information Processing Unit (Siemens automat). The communication between the detectors and the Central is achieved with Profibus DP via optical fibres to insure the quality of the data transfer. The states of the detectors are displayed in the Control Room on the process control screens. During the 10 months test period, the system showed its reliability for the detection in closed buildings although very dusty. No important evolution of the sensors was stated. For outdoor applications, the system showed good reliability but needs a periodic maintenance.
