Analog dial gage (left) and a digital linear potentiometer (right)

An analog dial gage (left) and a digital linear potentiometer (right with blue barrel) used to measure land-surface movement in response to aquifer system deformation at the USGS Nansemond extensometer. The potentiometer is the primary instrument for the extensometer with a resolution of about 0.00001 feet (0.003048 millimeters) and a travel range of 0.328084 feet (100
