Howard A. Schaevitz Technologies Inc. Pennsauken, N.J. Engineers continue to increase their use of linear-position and displacement sensors for providing real-time information to feedback-hungry PLCs ...

Certain electromagnetic devices such as differential transformers are effective at translating the displacement of a magnetic armature into an AC voltage, which is a linear function of the ...

• LVDTs produce a linear electrical output directly proportional to the position of a movable ferrous core of nickel-iron alloy. • Two secondary windings in the LVDT produce identical output voltages ...

Grade school math students are likely familiar with teachers admonishing them not to just guess the answer to a problem. But a new proof establishes that, in fact, the right kind of guessing is ...
