Demountable Mechanical Strain Gauge

Demountable Mechanical Strain Gauge

20 cm Gauge Length.

Useful for shrinkage estimation of concrete blocks during hardening, strain measurement in structural members under load, measuring opening and closing of cracks in structures, measuring relative displacement of structures and for monitoring insitu behavior of rock strata in excavated cavities. The instrument consists of a frame with a handle at one end and a dial gauge of 0.002 mm x 5 mm fitted at other end. The frame carries a fixed conical reference point on the handle side and a moving conical point on the dial gauge side.
