Field Instrumentation Technical Handbook is a useful compendium of physical constants, tables and information no engineer responsible for field instrumentation should be without. It has been required reading in many companies for many years. Download your free copy now.
In this paper, a model predictive controller is configured to simultaneously manipulate a small valve and a large valve, eliminating the problems inherent in split-ranged and valve-position controllers.
This safety information bulletin from the Energy Institute describes a practical approach that has been used to improve alarm systems at a petroleum refinery and to reduce the burden on operators caused by alarms. Guidance is available on the problems with alarms and what measures to take to improve alarm systems.
The inability to effectively manage control system alarms has been a long tolerated issue in the continuous process industry. This White Paper provides detail behind a solution to the total alarm management problem that takes into account the key elements and directly targets the real issues.
From telephones to remote TV controls to alarm systems, wireless is everywhere! It is the hottest and latest technological breakthrough. Or is it? This White Paper compares wired and wireless applications, and the benefits and limitations of this 100-year-old communications technology.
The fieldbus industry has responded to the disparate or non-existent interfaces to control systems and configuration tools with the introduction of two new complementary technologies FDT and Enhanced EDDL.
This White Paper maintains that by understanding the nature and causes for wasted time due to OEE (overall equipment effectiveness), decisive corrective action plans to increase productive time may be devised.
It seems like everyone is talking about alarm system rationalization or re-engineering projects these days. But sometimes these rationalization projects have trouble getting off the ground. This White Paper describes a way to justify the alarm rationalization project by installing an on-line alarm auditing tool.
There's no simple solution to achieving accurate temperature measurement. Its a combination of knowing the inherent accuracy of particular sensor types, but also how environmental factors can create further measurement uncertainty and the sensor calibration techniques available to reduce this uncertainty.
This guideline provides suggestions for an effective cyber security patch management strategy for control systems, addresses potential risks that can apply to some electricity sector organizations, and provides practices that can help mitigate the risks.
PID Loop Tuning Tips Pocket Guide has been expanded. Now it includes both open and closed loop tuning procedures, in addition to the original reference material of the first version. This eight-page publication was created to give engineers a short easy-to-use guide to tuning PID loops, and it includes a reference section that summarizes many of the more common controllers available.
PID Control (proportional-integral-derivative) is by far the widest type of automatic control used in industry. Even though it has a relatively simple algorithm/structure, there are many subtle variations in how it is applied in industry. This has probably resulted in confusion for plant engineers and operators, who are happy to leave control loops in a sub-optimal configuration.
