4-20 mA Instruments in Industries | Fieldbus Training

4–20 mA instruments are the backbone of industrial process control, widely used for transmitting analog signals representing process variables like pressure, temperature, flow, and level. This current-based signal is highly reliable, immune to electrical noise, and capable of long-distance transmission without significant signal loss. The 4 mA live-zero allows fault detection (0 mA indicates a break), while 20 mA represents the full-scale measurement. These instruments are essential in PLC and DCS systems, ensuring accurate monitoring, control, and automation across industries such as oil & gas, power plants, and manufacturing.
