The changing environment of discrete sensors

We've all experienced some sort of change within our lives that render us to question, why weren't things that way in the first place. Change, inevitably, is a part of life that helps you realize growth has occurred, for nothing is static. That idea rings true for various characteristics of discrete sensors.

When smaller, faster, and less expensive are not the final answers

In this space throughout the year, Control Engineering has covered PLCs, terminal blocks, board level products, test and measurement equipment, servo motors, control valves, and other products. Looking back, one theme is dominant: everyone wants smaller, faster, easier, less expensive components to get the job done.

Devices operate ‘standalone,’ have enhanced displays

Cellular phones, laptops, and palm pilots, oh my. If Dorothy Gale's family had access to test and measurement equipment to detect that legendary tornado, "The Wizard of Oz" story line would have been significantly different. Dorothy was instructed to "Follow the Yellow Brick Road to Emerald City where you will find The Wizard.

Do the locomotion of motors

"Come on, do the locomotion, I know you'll get to like it if you give it a chance. Do the locomotion, a chugga-chugga motion like a railroad train." -Grand Funk RailroadMotors, of various types, have provided profound changes in everyday life for over a century. Throughout recent years, however, they have undergone changes to more efficiently and effectively complete tasks in less time.

Increased standardization is in control valves’ future

'Control valves are devices with movable, variable, and controlled internal elements for modulating fluid flow in a conduit." (See CE, March 1997, Back to Basics: "Control Valves—Sizing, Design, Characteristics," p. 116.)Most people may agree with the definition of a control valve, yet there is renewed interest in European Mandatory Directives surrounding control valve terminology.

Changing sounds of DAC hardware

Since its inception during the 1500's, the violin has undergone very little change. Strings and bow still work together to perform vital functions that allow a musician to keep the instrument strumming in tune. Like the strings of a violin, data acquisition (DAC) hardware devices perform vital functions in many industries.
