WebThe 4-20 mA signal is not a communication protocol, the only thing it does is represent the full measurement of the sensor; i.e., the 4 mA output from your transmitter will equate to 0 (%, ppm) in your sensor and the 20 mA output will equate to the full range of the sensor's scale. To work, it needs to be some sort of sensor which measures a ... WebDec 2, 2024 · The choice of the loop load resistor usually depends on the input signal voltage the receiver system requires for good resolution. A 4-20 mA loop current will develop 2-10 VDC across a 500 Ohm load resistor (E = IR). If the receiver system will work satisfactorily with a lower input voltage, the 4-20 mA loop current will develop 1-5 VDC …

WebNov 28, 2024 · This signal is connected to an input on the control that measures the amperage and converts that to a reading. Because the amperage is the same at all points in the circuit, the 4-20ma circuit is not impacted by a voltage drop or interference like a voltage-sensing circuit. Because the “bottom” of the scale is 4ma, the control can also ... WebMay 7, 2024 · No separate power supplies needed. The 4-20mA sensor can be in a remote place with just a loop (pair) of wires running to it, and those wires carry both the power to the sensor and the signal coming back. This is the whole point of 4-20mA, the whole reason it was created in the first place.
