Borehole extensometers comprise of rods and anchors installed in a borehole to monitor displacements at various depths. A pre-set length of measuring rod is inserted into a nylon tube to avoid soil friction with the rod tip fixed to a groutable steel anchor. Relative movements between the anchors and the reference head may be measured manually with a caliper or automatically using linear transducers that are fixed to the reference head and connected to a datalogger for remote monitoring.
