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 ...

The AST5300 wet/wet differential pressure sensor from American Sensor Technologies, Mount Olive, N. J., measures the difference in pressure between two points, and, when used with signal processing, ...
