Silo/filter probes for your coal mill system. Highly combustible coal dust poses a serious hazard. CO builds up in coalfilled silos and in cyclones or bag houses that are not being used, while imprecise O2 levels in inert coal mills can also present a significant danger. In either situation, selfignition is a real possibility.
