There are three main advantages of an ideal 4–20mA current loop. First, the accuracy of the signal is not affected by the voltage drop in the loop, as long as the power-supply voltage is greater than ...

You might not have as ready access to current loop sensors and actuators as someone who works in industrial automation, and your project might not really take advantage of all the 4-20 mA standard ...

The low output voltage level of the analog sensor and the long distance to the control room together constitute significant system design challenges. Here are clues on how to solve them. The 4-20 mA ...
