Addressing the shortfall in process control systems
There is a shortfall or imbalance between the steady increase in the complexity of process-related technologies, and the much slower rate of increase in the sophistication of process control systems. This paper explores two avenues along which this imbalance can be attacked. The first would more aggressively exploit opportunities for incremental instrumental improvements, while the second ...

Teron SL670e and Teron SL670e XP: EUV Reticle Quality Control
Extreme ultraviolet (EUV) lithography is a key technology inflection for the semiconductor industry. While shifting the scanner wavelength to EUV has enabled printing of the smaller pattern features required for ≤5nm design node chips, it has also added tremendous complexity to the equipment, reticles, resists and other infrastructure required to support EUV lithography. New defect mechanisms ...

How Does an Electric Valve Actuator Work?
Electric valve actuators control the opening and closing of valves. They can provide either linear or rotary motion and work with different types of valves, including ball and butterfly valves. Electric valve actuators respond to prompts through remote control or centralized process control systems, which make them invaluable for managing systems that are hard to reach or spread across a large ...

Why many control systems fail. Water Environment and Technology
Abstract: When implementing real-time process control systems at wastewater treatment plants (WWTPs), several technical problems may have to be addressed. Sensors have to be reliable. Controllers should be properly designed and tuned. Fault detection should be implemented and safety nets designed. Actuators must have adequate control authority to deal with changing influent quality and quantity. ...

Level and limit level detection with ProGap - Case Study
Application During the process of mining gypsum in a stone quarry, gypsum rock is transported via a series of conveyor belts to the production line. Certain critical conveyors are located remotely from the production line and therefore not visible and suspect to blockages. The customer wants to avoid material overfl ows and blockages between the conveyor belts and a transition chute. Because of ...

Process Control Systems at Water Resource Recovery Facilities: Use of Process Simulation to Assist with Controller Design and Tuning. Proceedings ISA2017
Abstract: Process simulation is a useful tool to assist with control design and tuning at water resource recovery facilities (WRRFs). Simulation models serve as virtual WRRFs which can be used to design, tune, and test control systems. In addition, simulation models can be used as a basis for generating the models used in model-predictive control systems. Most WRRF simulation platforms provide ...
