Model PTG71 / 72 - Smart Pressure Transmitter

Power supply and external load resistance

External load resistance should be determined in relation to the voltage of the power

supply so that both fall inside the diagonally-shaded area below.

External load resistance is the total resistance connected to the output terminals of the

Transmitter, which includes the resistance in the cables forming the loop, the internal

resistance in instruments connected between the Transmitter and the power supply,

etc.

The abscissa axis shown in the figure is the voltage of the Transmitter’s power supply

and the ordinate axis is the external load resistance.
