The Pulse of Industrial Automation

To identify and keep track of key developments and trends, you have to be on the road constantly. Shows and expos provide glimpses of the forces and technologies that are shaping automation. Here's what I've seen this month.

Process Analytical Technology and Quality Assurance

My visit to INTERPHEX last month confirmed the predominance of process analytical technology (PAT) in the pharma and food-processing industries. The goal of PAT is to understand and control quality in manufacturing through statistical control processes.

The strong culture that embodies PAT has been built in less than 10 years under the urgings and dictates of the Food and Drug Administration (FDA). This culture is reinforced and spread through education programs, such as the 150 short courses and advanced seminars offered this year by The Institute for Applied Pharmaceutical Sciences of The Center for Professional Advancement.

Visits with sensor and control vendors at INTERPHEX showed me that the big automation system houses—such as ABB, GE, Emerson Process, Honeywell, Invensys, and Siemens—and smaller outfits and instrument specialty companies—such as Weed Instruments, WIKA, and Burns Engineering—are supporting PAT through a strong focus on the National Voluntary Laboratory Accreditation Program and products.

It's no wonder that PAT has such a strong hold on these industries. In addition to being in line with the economic interest of manufacturers and the well-being of consumers, PAT is mandated by FDA. That's more initiative than you get in most industries to do things right.

This is borne out by the clear distinction between the trend in the food-processing and pharma industries and similar efforts underway in the automotive and other manufacturing industries. In automotive, the evident foot-dragging by U.S. companies is reshaping the industry's hierarchy. Toyota has surpassed Ford in car volume and profits, and it may well do the same with GM on an annual basis very soon (it did so last quarter). Catch-up is really hard when the guys you are chasing are moving faster than you and making real money to boot.

I have plaques on my wall from courses I took from Tennessee Associates 17 years ago covering the same subjects, with the same goal: product quality assurance. I was working for a U.S. steel company at the time, and the quality initiative had been impressed upon us by the automotive industry. We called it statistical process control, or SPC, but the goals and the methods were the same.

My former employer went out of business five years ago because too many of its top and middle managers were not convinced of the truths in the quality initiative. In fact, the entire industry suffered. The initiative was not implemented very well, and the industry never really embraced it. They also didn't have an FDA to keep them on the straight and narrow path to success in product quality.

TempMeko 2007 and IMEKO

On another front, the tenth International Temperature Symposium, TempMeko was held this month in Lake Louise, Alberta, Canada. TempMeko is managed by the Temperature Committee, TC12, of IMEKO, the International Measurement Confederation.

Occurring only once every three years, this is the first time the meeting has been held in North America. I hope it comes back before another 30 years have passed.

IMEKO is also holding its sixth International Conference on Measurement this month in Slovakia.

Both shows are worth checking out.

Thanks for reading. See you next month.
