Neural Network-Based Actuator Fault Diagnosis for a Non-Linear Multi-Tank System [Technical]
Appropriate actuator fault estimation allows for the application of various fault tolerant control strategies enabling compensation of the faulty actuator by increasing performance of the other actuat -
AutoQuiz: What Is the Best Tuning Method for a Catalyst Feed Flow Controller?
Only a closed-loop tuning method can be used with an exothermic reaction where the reactor can "run away" (increasing speed of reaction as the reaction progresses, catalyzed by its own heat of reactio -
How to Bridge the Generation Gap in the Process Industries Through Mentoring
One of the key benefits mentoring is the stability it brings to industrial automation and the process industries when done effectively. -
How Industry 4.0 and Digitization Improves Manufacturing Responsiveness, Quality, and Efficiency
Automation is essential to the implementation of Industry 4.0 and IoT strategies as manufacturers realize low labor rates are no longer a winning strategy. -
AutoQuiz: Plotting Control Valve Characteristics
For an equal percentage valve characteristic, each increment of valve movement provides the same percentage increase in flow. -
Engage in Important ISA Activities, Events and Opportunities During the Summer
Focus on upcoming events and training opportunities, governance activities, and ISA's extensive cybersecurity training programs and resources. -
How to Leverage the ISA Ecosystem to Advance Your Career in Industrial Automation
The automation industry is experiencing rapid changes and challenges; the diversity of ISA members is a great resource of experience, ideas, and know-how. -
Do Government Pipeline Regulations Improve Safety?
Conditions encountered by pipelines in the U.S. are diverse and the complexity motivates broad and cautiously general requirements. This is not the case at the borders of all sovereign nations. Diverg -
Webinar Recording: Strange but True Process Control Stories
Listen to Greg McMillan's lessons learned the hard way during a 40-year career in process control industries. Many of the mistakes made in the field are still being made today, some posing safety risk -
What Is the Value of Standards-Based Cybersecurity Conformity Assessments for Industrial Automation and Control Systems?
The industrial automation and control system (IACS) community must recognize the value of the ISA/IEC 62443 IACS family of cybersecurity standards. -
AutoQuiz: Characteristics of a Full-Wave Bridge Rectifier Circuit
A bridge rectifier consists of diodes in a bridge circuit configuration. It features the same output polarity for either input polarity, and is used for converting an alternating current (AC) input in -
Self-Powered Wireless High Temperature Electrochemical Sensors [Technical]
Reliable wireless high temperature electrochemical sensor technology is needed to provide in situ corrosion information for optimal predictive maintenance to ensure a high level of operational effecti -
IO-Link Connects Intelligent Sensors and Actuators in the Process Industries
IO-Link is being used in a wide range of applications as an open standard for smart sensor I/O, primarily for discrete devices. IO-Link is a point-to-point network communications standard and protocol -
AutoQuiz: What Is the Cause of Cavitation in a Liquid Flow Stream?
When fluid drops below a liquid's vapor pressure, a gas is formed. As fluid moves downstream to where the fluid pressure is greater than the vapor pressure, it "collapses" back into a liquid. -
Webinar Recording: How to Avoid the Most Common Mistakes in Field Calibration
Instrument calibration in the process industries requires the proper process, tools and parameters for each instrument application to ensure valid results. If one of the three are lacking, your result -
What Are the Obstacles to Commercial, Off-The-Shelf Systems for the Process Industries?
Industry sectors with critical real-time control requirements are constantly integrating commercial off-the-shelf technologies into their automation systems. Industrial automation end users are demand -
AutoQuiz: How to Read a Gauge Pressure Transmitter
At zero gauge pressure in the steam line, you are essentially suppressing (pushing) the transmitter output back down to zero after the system reaches equilibrium. The transmitter will read that impuls -
Can Risk Analysis Really Be Reduced to a Simple Procedure?
Geographically diverse systems using integrated technology are inherently complex. A structured way of analyzing them can be very helpful. -
How to Permanently Reduce Operating Costs in Your Maintenance Department
Most managers in the process industries still look at maintenance only as a cost center, reducing operational costs in the maintenance department is often the first thing on their list. That puts a lo -
AutoQuiz: Failures of Complex Systems in SIS Design and SIL Selection
A fault tree analysis begins with the "top event," which is the result of a number of basic events that contribute to, or initiate, the system failure.
