The 4–20mA current loop has been widely used as an analog communication interface in industrial applications. It facilitates transmission of data from remote sensors over a twisted-pair cable to a ...

D c = DAC code for a 4–20mA current output. G N = nominal gain = 1.27755. O N = nominal offset = 31005.1 . In reality, the calibration is needed for analog components used in a smart-sensor front-end ...

It is suitable for measurement of 4-20mA control loops, 4-20mA signal measurements, testing analogue input/output signals and other low-level DC current measurements. The Fluke Connect system allows ...

The concept is disarmingly simple and effective: the signal of interest, whether from a sensor or to an effector transducer, uses 4 mA to represent the lowest signal value and 20 mA for the highest. .
