FactoryRegistry lists 3,982 facilities whose primary industry classification is one of the 4 industries above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced parts for industrial process control instruments (excluding parts for automatic residential and commercial environmental control systems and for major appliance controls), in the shares shown above, and does not say which establishments. Where a plant’s own website or a federal registry names what that plant makes, it appears on the plant’s own page with the source named.
