Modern DCS Graphics: Level 1 Overview Displays

Editor’s Note: ANSI/ISA-18.2-2009, Management of Alarm Systems for the Process Industries and ISA-101, Human-Machine Interfaces are valuable standards for users designing level 1 displays. Level 1 display design cannot be a one-size-fits-all approach. What may work for operators at one company may not work for others somewhere else. The challenge is to find the balance […]

Modified Smith Predictor-Based Cascade Control of Unstable Time Delay Processes

  Abstract: An improved cascade control structure with a modified Smith predictor is proposed for controlling open-loop unstable time delay processes. The proposed structure has three controllers of which one is meant for servo response and the other two are for regulatory responses. An analytical design method is derived for the two disturbance rejection controllers by […]

How to Overcome Challenges of PID Control and Analyzer Applications via Wireless Measurements

Wireless measurements offer significant life-cycle cost savings by eliminating the installation, troubleshooting, and modification of wiring systems for new and relocated measurements. Some of the less recognized benefits are the eradication of EMI spikes from pump and agitator variable speed drives, the optimization of sensor location, and the demonstration of process control improvements. However, loss […]

How-to-Calibrate-Analytical-Instruments

Webinar Recording: How to Calibrate Analytical Instruments

This is the first of a series about maintaining analytical instrumentation. Insight into common applications and issues of analytical instrumentation as well best practices to calibrate will be explained. The webinar will provide examples of how you document “one-sided” calibrations, such as pH/ORP and gas sensors/analyzers. This approach can apply to other instrumentation as well, […]
