The signal output of the AMC-2751 sensor/transmitter is a 4 to 20 mA DC current, therefore
it can be connected to computers or data-loggers equipped with an analog-to-digital converter.
In many cases a load resistor is required to convert the 4 to 20 ma current signal to a voltage
signal, as shown in Figure 5.
