Laboratory sample of high-speed multithreshold control gauge of the emergency and preemergencies in an explosive atmosphere

In this paper we consider the problem of designing laboratory sample of high-speed multithreshold control gauge of the emergency and preemergencies in an explosive atmosphere. We designed the optical system and the electronic part of the gauge. We considered the determining technique of the gauge operate time with experimental unit for the explosions of dust-methane-air mixtures. The results of the experiments were present.
