Silo/filter probes for your coal mill system. Highly combustible coal dust poses a serious hazard. CO builds up in coal-filled 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, self-ignition is a real possibility.
