Book Excerpt + Author Q&A: Driving Business Value in Industrial Innovation
The emerging frontier for industrial innovation points at exciting changes likely to revolutionize the business of manufacturing. -
Feedforward Control Enables Flexible, Sustainable Manufacturing
Feedforward provides preemptive corrective action for production rate and grade changes enabling key PID controllers to provide consistent product quality. -
AutoQuiz: Why Are Gathering Requirements Critical to the Success of an Automation Project?
Gathering requirements are important because they define the objectives, purpose, scope, needs, and other key meters. -
AutoQuiz: What Is the Process for a Continuity Check of a Field Transmitter?
A continuity check is performed on a length of finished wire or cable to determine if the electrical current flows continuously throughout the length. -
AutoQuiz: How to Measure and Compensate for Disturbances to Prevent Set Point Deviance
The objective of feedforward control is to measure disturbances and compensate for them before the controlled variable deviates from set point. -
Design and Analysis of a Model Predictive Controller for Active Queue Management
An ISA technical paper proposes a model predictive control as a novel active queue management algorithm in dynamic computer networks. -
AutoQuiz: What Is the Dead Band of an Instrument?
The dead band is the range through which an input signal may vary, upon reversal of direction, without initiating an observable change in output signal. -
Industrial Pervasive Sensing Reduces Costs and Prevents Downtime
Industrial pervasive sensing devices lower energy requirements and reduce maintenance costs. -
AutoQuiz: How to Simultaneously Optimize an Interacting Dead-Time Dominant Process with Multiple Constraints
Model predictive control excels at dead-time dominance and simultaneous optimization while accounting for future prediction of proximity to constraints. -
AutoQuiz: What are the Closure Members in Globe and Butterfly Valves?
A butterfly valve has a circular body and a rotary-motion disk-closure member. The physical blocking mechanism in a globe valve is a plug. -
AutoQuiz: How to Define the Flow Characteristic for a Valve
A linear flow characteristic is when flow capacity or (Cv) increases linearly with valve travel. Flow is directly proportional to valve travel. -
AutoQuiz: How to Detect a Fault in a Safety System
A proof test on a system may reveal faults that would otherwise not be mentioned by internal diagnostic measures and is therefore correct. -
AutoQuiz: How to Calculate the Output Signal Value of a Pneumatic Transmitter
There is a straightforward linear relationship between the units of pounds per square inch (psi) and degrees F (Fahrenheit). -
AutoQuiz: What is the Cause of a High Process Variability?
An oversized control valve will operate next to the seat where the friction and stick slip is greatest. -
AutoQuiz: How to Calculate Temperature for an Electronic Transmitter
There is a straightforward linear relationship between the units of milliamps and degrees. -
Electromechanical vs Digital: Time to Make the Switch?
Electromechanical switches have their place in the modern plant, but a digital upgrade could pay off in many applications -
Book Excerpt + Author Q&A: Measurement Uncertainty
The new, expanded fifth edition of ISA's book on measurement uncertainty presents a variety of uncertainty experiments as well as several new appendices. -
AutoQuiz: How to Calculate Dead Time from Transportation Delay for Thickness Control
The time it takes the sheet to go from the diebolt actuators to the thickness gauge that transverses the sheet is the transportation delay -
Building on ISA’s Financial and Operational Success
Steven Pflantz, president of ISA 2017, pledges to build on ISA’s financial and operational success by leveraging core strengths and capabilities. -
How to Succeed with the Industrial Internet of Things
To achieve success with the IIoT, industrial businesses and manufacturers must create a long-term vision with an associated value proposition,
