The MC-6415 Active Sampling Smoke Sensor overcomes problems, which have inhibited the performance of other smoke sensors used in mining, such as misinterpreting dust material as smoke and the continual clogging of the sensor sampling system. This sensor resolves these issues by using a unique air path, which eliminates a large percentage of environmental contaminants and controls the quality and quantity of air being sampled. Both wired and wireless versions of the sensor are available.
