3-Dimensional Crackmeter
The Crackmeter consists of two half-gauge fixtures, one mounted on
each side of the crack. A portable dial indicator is inserted into one
of the three stainless steel sleeves of the gauge fixture until it shoul-
ders, and its tip is in contact with the opposite stainless steel gauge
surface. The dial indicator shows the relative distance between the
two gauge fixtures. A change in this distance indicates movement in
the joint. The other two gauge axes are read in the same manner.
