How To Make 4-20 mA Current Loop Measurements

WebIt is also possible to connect a shunt resistor within the circuit itself and directly measure the current, as in the classic ammeter and current shunt. We will look at both methods in the sections that follow. Open loop vs. closed loop current sensors. You may hear about the open-loop and closed-loop current sensors. WebLEM Hall Effect current sensors are available in open-loop, closed-loop and Eta configurations. Open-loop Hall Effect sensors are highly cost effective, as well as being small and consuming minimal power. Closed-loop sensors offer higher accuracy and enhanced speed to enable currents with a wider range of frequencies to be measured.
