Tons of Technologies Hit Houston

They may or may not beat the Texas heat, but visitors and exhibitors at ISA Expo/98 will certainly find what they need to clobber competitors at this year's event.Billed by organizers as the biggest control and instrumentation show ever, ISA Expo/98 is the second alternate-year-format event for ISA, the international society for instrumentation and control (Research Triangle Park, N.

Structured programming tools for embedded systems

Sometimes it's fun to imagine what the world might have been like if John von Neumann had a room full of Crays or if Galileo had the Hubble telescope. On a somewhat smaller scale I wonder what my own career might have been like if I'd had something besides machine code back in the days of designing embedded control systems for microwave ovens, simple RTUs, and steam-driven chiller packages.

Software Still a Control ‘Hit’

Data acquisition software is hardly a "new kid on the block." The commercial use of software-configured control systems dates back to the 1970s, when the first large-scale proprietary control systems debuted. As the control industry has evolved, so have software-based systems.With the evolution of the personal computer and the networks on which they "reside," software developers are produ...

Simulation Simplifies ‘What-If’ Analysis

Whenever a new control system is proposed for an automated plant, a manager, engineer, or operator invariably asks how the system will react to certain events or conditions in the plant. What happens when the ambient temperature drops below freezing? What will the control system do if the conveyor suddenly stops? Will the robot arm be able to squeeze through that opening with a part in it...

Component modeling tool

Pittsburgh, Pa. —PEmag is a design tool tailored for the design of power electronic device components, such as inductors and transformers. It allows the designer to enter standard geometry dimensions for the components and perform fast analytical solutions. It automatically generates and solves a finite element-based model using Ansoft's Maxwell 2D Electromagnetic field simulator to ensu...

Electromechanical system design tool

Pittsburgh, Pa.— Electromechanical System Simulator (EMSS) software provides the designer with tools to analytically understand the interaction of currents, voltages, and mechanical loads and motion within an electromechanical device prior to its production. When used in design of electric motor systems, transformers, sensors, or actuators, EMSS uses time integration and nonlinear iterat...

Flowmeters Pass the Muster

Measuring the flow of fluids is critical in many industrial plants. For some applications, measuring flow accurately can make the difference between making a profit or taking a loss.Application media = technologyFlow measurement is media dependent. According to a study of flowmeter makers and worldwide users recently conducted by Automation Research Corp.

May We Have the Envelopes Please

"Control products just keep getting more advanced, yet simpler to use,"was the consensus among editors at Control Engineering when it was time for them to choose the best control products of 1997. For the 11th consecutive year, the editors chose the 50 best products based on three criteria: technological advancement, impact on the market, and service to the industry.
