Whitepaper: Windmill applications, signal conditioning tips
Windmills can operate for six months or more without any maintenance or supervision in rugged locations. Dataforth whitepaper offers advice on signal conditioning and what I/O connections need to be monitored in extreme environments.
Windmills can operate for six months or more without any maintenance or supervision. They operate in some of the worse environmental conditions imaginable; all seasons of the year, in temperature extremes, in lightning storms, snow storms, high summer humidity as well as in dry arid extremes.
Dataforth offers advice for signal conditioning in a white paper that recommends what I/O typically needs to be monitored and what controllers are best suited on a windmill to provide the safest and longest trouble-free operation. Moreover, due to the special environmental nature of the application, it offers advice on what signal conditioning hardware should be used to assure successful operation.
Because wind turbines generate high voltages and currents, electrical components must withstand high surge voltages and be immune to the electrical noise that can radiate from generators and switch networks. Dataforth says
- Meet the requirements of EN61000-6-2 (ESD/RF/EFT immunity).
- Provide 240 V ac continuous input protection, 1500 Vrms transformer isolation, and ANSI/IEEE C37.90.1 transient protection.
- Deliver secondary protection against lightning strikes and other overvoltage events.
Wind turbines, like many types of industrial-grade machines, demand reliable and broad ranging protections. For more information, including a cutaway diagram of a wind turbine, see the Dataforth white paper on "Wind Turbines Today ."

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
