Going against the grain dust

摘要

As the owner of an industrial-controls company, I frequently receive calls from customers. Recently, a representative from our best customer called, asking for help with a sensor on a monitoring system. The company happens to be in the same city as ours, so I was able to visit the site. Our company manufactures an intrinsically safe monitoring system for conveyors and other equipment in hazardous locations and other industrial and commercial facilities. The principle of intrinsic safety is to restrict the amount of available energy in the field wiring system to less than the amount that could cause an explosion or a fire.
