ABSTRACT:
A new and useful wireline extensometer is provided that uses a tensioned cable extending between a supply spool and an anchor (e.g. of a type connected to a slope mass), measures movement of the cable to reflect movement of the anchor (e.g. due to movement of the slope mass), and includes a magnetic brake configured to provide a predetermined constant non-frictional braking force on the supply spool. The preferred wireline extensometer is designed to (i) minimize the risk of the extensometer reporting data that suggest slope movement where the slope mass has not moved to an undesirable extent, (ii) measure slope movement at relatively slow rates as well as rapid rates, and to (iii) measure slope mass movements continuously, and in a manner that can be efficiently and effectively communicated to responsible personnel.
