How Industrial Engineers Use Social Media

I have been tracking how the industrial automation community uses social media since the “early days” — back in the mid-2000s. Some companies took a “wait-and-see” approach, understandably concerned about the business prospects for social media after highly touted platforms such as MySpace, Second Life and Google Buzz fizzled. Last year, digital marketing expert and […]

The Good, Bad and Ugly of Thermal Mass Flowmeters

Thermal mass flowmeters can be a relatively inexpensive flowmeter that can handle extremely small flows (e.g., inline 1/16-inch meters) and large flows (e.g., multipoint insertion type in 60 inch ducts). Thermal flowmeters introduce heat into the flow stream and measure how much heat is absorbed using one or more temperature sensors. However, the meter requires […]

Tracy-Widom Approach to F-16 Aircraft Sensor-Actuator Fault Detection

Abstract: The fault detection approach based on the Tracy-Widom distribution is presented and applied to the aircraft flight control system. An operative method of testing the innovation covariance of the Kalman filter is proposed. The maximal eigenvalue of the random Wishart matrix is used as the monitoring statistic, and the testing problem is reduced to determine […]

ISA Technical Education and Training for September and October

In September, drill down on process control with ISA’s Process Automation Boot Camp. Designed for non-maintenance personnel with little or no background in process measurements and control, this hands-on course focuses on the physical measurement technologies, the communication signals, and various applications of instrument equipment to achieve common process measurements and control. An exciting mix […]

AutoQuiz: How to Measure the Level of a Liquid with a Dielectric Constant

Today’s automation industry quiz question comes from the ISA Certified Automation Professional certification program. ISA CAP certification provides a non-biased, third-party, objective assessment and confirmation of an automation professional’s skills. The CAP exam is focused on direction, definition, design, development/application, deployment, documentation, and support of systems, software, and equipment used in control systems, manufacturing information […]

How Does Low Flow Affect Differential Pressure Flowmeter Calibration?

For flowmeter calibration, the phenomenon of “low flow cut-off” is only associated with differential pressure transmitters with square root extraction — if the square root (flow) calculation is done in the control system (DCS/PLC), then this test approach does not apply. The graphic below illustrates the issue. Some may ask why we are testing the […]

The Decision to Volunteer: The Why, How, and a Personal Call to Action

In their book, The Decision to Volunteer: Why People Give Their Time and How You Can Engage Them, Beth Gazley and Monica Dignam used research on associations to better understand why members volunteer for professional societies such as ISA.  Their research indicated that volunteers contribute their time for both altruistic (other-serving) and instrumental (self-serving) reasons.  […]
