Borehole extensometers (single-point or multi-point) are instruments designed to measure axial displacement of a fixed point or points along its length. Extensometers can be a rod-type, or a wire-type and are usually grouted into an uncased borehole. They can be installed horizontally, vertically, or at any angle.<ref name="Glossary">[[Federal Guidelines for Dam Safety: Glossary of Terms (FEMA P-148)| Federal Guidelines for Dam Safety: Glossary of Terms (FEMA P-148) (FEMA, 2004)]]</ref> | Borehole extensometers (single-point or multi-point) are instruments designed to measure axial displacement of a fixed point or points along its length.
