Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...
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 ...
My recent DI contribution (Another silly simple precision 0/20mA to 4/20mA converter) used the LM337 regulator in a novel circuit arrangement to translate an input 0-20 mA current source into a 4-20 ...
