Voltmeters and ammeters are used to measure voltage and current
... The two crucial characteristics of any galvanometer are itsresistance and its current sensitivity. Current sensitivity is the current that gives a full-scale deflection of the galvanometer's needle -- in other words, the maximum current that the instrument can measure. For example, a galvanometer w ...

Bridge-Type Sensor Measurements are Enhanced
... Resistance-based bridge circuits are widely used to provide electrical outputs from sensors measuring physical variables, such as pressure and force. These outputs are usually small—and thus require amplification to bring them up to levels required by A/D converters in measurement-and-control system ...
