<p>A current monitor comprises a current detecting section interposed between two transmission lines for outputting a physical amount measured by an instrument by converting it into a signal current and detecting a current value outputted onto the transmission lines, and a power supply voltage generating section interposed between the transmission lines and outputting a voltage generated when the signal current flows. The current detecting section is driven with a voltage outputted from the power supply voltage generating section.</p> |
