Current sources are widely used in industrial control systems to transport analog process signals over long distances, but they are less widely used than voltage sources. This post loosely reviews the ...

Analog transmitters have evolved from simple 4- to 20-mA current loops to designs that include µCs for signal conditioning at the transmitters and designs that allow bidirectional digital ...

Machines need sensors and transmitters to operate reliably and consistently. All it takes is a small drop in air pressure or a slight jam to cause a machine to crash; these sorts of problems can often ...
