A more dependable estimate of the value of manufacturing to the U.S. economy is data from the U.S. Census Bureau (www.census.gov), which recently released some new data from its 2011 County Business Patterns and Survey of Manufacturers projects. The first thing I found interesting in this release is that number of manufacturing facilities in the U.S. still hovers around 300,000 – which is pretty much where it was in 1990. While it\’s clear that offshor-ing impacted millions of jobs and lead to the shut down of numerous manufactur-ing facilities, the overall number of manufacturing facilities in the U.S. has remained fairly stable over the past 20 years. Some will argue that this number should have grown significantly if it weren\’t for all the offshoring, but what happened happened. What\’s important now is the current state of the industry and forward-looking trends. Looking at some of the key figures reported in the Census Bureau\’s release, manufacturing is currently the fourth largest employer in the U.S., employing 11 million people. This means that manufacturing trails only healthcare, retail and hotel/food services industries in terms of employment. The average annual salary of a U.S. manufacturing worker was $52,300 in 2011 – 27% higher than the average U.S. worker\’s salary in 2011 (which was $41,211 in 2011, according to the Social Security Administration). Considering the importance of exports to the economy, it\’s notable that manufacturing still accounts for more than half of our export dollars – 6 in 10 of U.S. export dollars were generated by manufacturing in 2011. Of course, exporting is only half the economic equation, with consumption being the other half. According to the 2011 Annual Survey of Manufacturers, U.S. manufacturers spent $3.2 trillion on materials in addition to spending $147 billion on capital expenditures. Sectors of the manufacturing industry that are performing the best, in terms of shipment value, are: petroleum and coal products ($837 billion), chemical ($777 billion), food ($710 billion), and transportation equipment ($690 billion). From there, the size of the industry sectors, in terms of shipments, are consid-erably smaller, with the next category – machinery – clocking in with $366 billion in shipments, about half of the shipment value total of the equipment sector. In terms of energy management, data from the 2011 Annual Survey of Manufacturers shows that manufacturers – the largest industrial consumers of energy – are getting more savvy about generating power and making money from it.
Nicht nur Motoren und Pumpen sind in Produktionsanlagen dem Verschleiß unterworfen, sondern auch die Datenleitungen der Maschinen- und Anlagennetzwerke einschließlich Kabel und Stecker. Während der mechanische Verschleiß analog wahrnehmbar ist, macht sich der Verschleiß einer Datenleitung erst im Extremfall bemerkbar: dem Ausfall. Um dem entgegenzuwirken, empfiehlt Indusol den Einsatz von intelligenten Managed Switches, mit denen der physikalische Zustand der Datenleitung digitalisiert und somit sichtbar gemacht werden kann.
