What is 4-20mA?
4-20mA current loops are a common industrial signaling standard used for transmitting sensor data. A 4mA signal typically represents the lowest value (e.g., zero pressure or temperature), while 20mA represents the highest value the sensor measures. This standard is robust against noise and voltage drops over long distances and can also be used to power the sensor.
