This application note’s primary goal is to provide an easy-to-understand primer for users who are not familiar with 4-20mA current-loops and their applications. Some of the many topics discussed ...

Process-control applications usecurrent loops to send informationas an analog signal over long distanceswith high noise immunity. Using thethree-chip circuit in Figure 1, you canmeasure alternating ...

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 ...
