The 4-20mA current loop is the dominate standard for sensor systems in many industries. This is because it is the simplest option to configure and connect. However, it also uses less wiring and connections than other signals, therefore reducing the overall system cost. In large locations, it is better for traveling long distances since the current doesn't degrade (unlike the voltage).
This winning combination shows a possible transmitter solution with our precision digital power monitor (DPM), stable power source, and the low power processing capabilities of our Arm® Cortex® RA2A1 MCU.
