The Industrial Internet of Things demands engineers with new skillsets

Along with MEs and EEs, we're going to need data scientists, system engineers, developers and systems integrators

My past month has been full of conferences and conference calls, and most have related to the Industrial Internet of Things (IIoT). Each has begun with presenting evidence of what a big deal it is and gone on to explain why. The common threads are an explosive increase in machine-level information (Big Data) and connectivity (on the Internet and in the cloud) that we can now profitably harness with analytics and software. So we must and we will, and we'll need your help. For example, for condition monitoring, we used to make rounds and enter data manually. Now we can gather much more information automatically. "Sensors are more accurate than people with clipboards, and…

Beginner's guide to differential pressure level transmitters

By David W. Spitzer

The importance of level measurement cannot be overstated. Incorrect or inappropriate measurements can cause  levels in vessels to be excessively higher or lower than their measured values. Low levels can cause pumping problems and damage the pump, while high levels can cause vessels to overflow and potentially create safety and environmental problems. Vessels operating at incorrect intermediate levels can result in poor operating conditions and affect the accounting of material. Learn more.

Controllers: Direct vs. reverse-acting control

By Bela Liptak

Valve failure position is determined by safety considerations. If, in case of failure, you want your column to go on full reflux, your selection where the reflux control valve is fail-open, and net overhead control valve is fail-close, is right. Assuming that the valve actuators are spring-operated pneumatic ones, and assuming that you define "failure" as the loss of air supply, the spring will act to open a fail-open (FO) valve and to close a fail-closed (FC) valve, regardless what the controller actions are.

What's wrong with my thermocouple? How do I know my RTD measurement is accurate?

Our experts tackle these not-so-simple problems

By Bela Liptak

Q: Thermocouple Diagnosis Our Type K thermocouple at 25 ºC generates 1.0 mV. It has a long TC cable which does not show continuity, but 130 ohms resistance. Can you explain why this is occurring and how it can be fixed? Ashish Garg  ashishgarg.ecb@gmail.com A: One of the problems associated with…

Best Control Valve Flow Characteristic Tips

Often arguments as to whether a linear or equal percentage trim is best are based on the theoretical inherent flow characteristics. Valve rangeability is often stated as simply a deviation of the catalog flow characteristic from the theoretical characteristic. Here we will see how the consideration of the changes in process dynamics, available valve pressure drop, and control valve dynamics can alter what you consider as the best flow characteristic.
