In the world of instrumentation, there are a number of different topics discussed and analyzed.  However, one that should not be overlooked is that of instrumentation fittings. Do you know what technologies are available? Do you know the strengths and /weaknesses? Are there any new trends?

For automating machines that require only two to three axes of electric actuators, pulse outputs may be the simplest way to go.

An operator in a fluid handling process is only as effective as his ability to work with a given controller. If there are factors that keep this individual from doing what is necessary for a smooth operation, adjustments need to be made.

When manufacturing engineers are tasked with automating a process that is currently done manually, their main question for an automation supplier is, “Have you ever automated this specific process before?” In complex applications, the answer is typically, “no.” Even simple applications can be more complex than at first glance.

In Joe Nettemeyer's long and productive career, he has had a front row seat to a significant amount of change, and he’s learned how to help others embrace transition. Nettemeyer spoke to Industrial Distribution Magazine about guiding everyone—even the skeptics—through major business shifts.

For many years, the industry has been guided to a liquid filter cartridge with an outside diameter (OD) measuring 2.5” or so with an inside diameter (ID) measuring 1”, and a length that varied from 5” to 40”. Of course, there are always a few exceptions to the length, but in general, these specifications were very much the standard.

Closed-loop stepper motors may be the best choice for tasks typically done by servos because traditional steppers couldn’t handle them.

A plant operator’s biggest fear is an unplanned shutdown. The process can place a heavy amount of stress on both operations and maintenance personnel. Alternatively, taking full advantage of a planned shutdown or turnaround is critical.

Developing a strong preventative maintenance plan for plant shutdowns and turnarounds is the best way for operators to minimize the risk of equipment failure, which can lead to unnecessary shutdowns and ultimately, higher costs.

In today’s refining and chemical manufacturing environments, the devil is always in the details. Choosing the right process design and the right equipment to ensure you’re operating efficiently without significant downtime is always a challenge. Your organization’s reputation, product quality, worker safety, and cost control are on the line all day, every day.

Today, the average computer chip is comprised of more than 10 billion individual transistors that require more than 1,000 steps to assemble into working components. Estimates show that the loss of just one die per wafer can equate to more than U.S. $1 million in lost revenues each year. And, a major contributor of faulty dies is contaminant particles.

Predicting your plant’s future depends on collecting and analyzing the correct type and amount of equipment and process data. Predictive maintenance (PdM), much like “IIoT,” “Industry 4.0,” and “Plug ‘n’ Play,” among other terms, may be an exciting concept in plants, but many still aren’t leveraging it fully.

Specifying control valves and engineering a system in which the flow of a particular product is completely optimized for superior performance and yield can be a challenging process.

Inside of plants today, AC motors are becoming the industry standard. Many plants are shifting to AC motors from hydraulic motors and in some cases DC motors when powering heavy loads, which were more popular in the past. This shift can be attributed to a variety of reasons and most have to do with cost. 

For automation applications, one of the larger misconceptions in the industry today is that when someone uses the phrase “motion control,” they can just as easily use the term “robotics,” as if the two are interchangeable.
