An iPhone as your next HMI? - Consumer-grade smartphones and tablet computers are fast becoming commonplace extensions of industrial networks, permitting process monitoring and, even (gasp!) process control.

Direct-drive wind turbines flex muscles - A different drive train design that eliminates the gearbox between a turbine’s rotor and generator is
attracting wind turbine manufacturers in the quest for higher power output, increased offshore reliability, and potential cost savings over the system’s lifetime.

Laser spectroscopy for measuring moisture in natural gas - Spectroscopy avoids sensor degradation possible with direct contact analysis methods resulting from
contaminants in the product stream.

M2M in manufacturing - Machine-to-machine technologies are moving into new markets and making machine processes and network connections more efficient.

High-efficiency gas turbines add new flexibility - Siemens’ H-class gas turbine, the largest machine of its type in production, recently broke the 60% net thermal efficiency barrier in combined-cycle (CC) operation. Other gas turbine makers with efficient machines also are exploiting design and control advances in CC power plant applications—and in evolving hybrid CC plants that incorporate renewable energy.

Inside Machines

Automated measuring system - New control system for an automated measuring system testing improves communications and saves space.

Winding technology in the drive - Winder applications that can be integrated into drive systems by setting parameters, rather than configuring and programming, provide an advantage.

Fly me to the moon - Tiny motion control technology helps with a prototype lunar mechanical tool changer for a robot that could unload moon landers from a spacecraft and then do various science experiments.

How to choose a motion control architecture - Building a controller has never been easier—or more confusing. This tutorial guide can help determine which motion control architecture to use.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
