The Linear Potentiometer Crackmeter is a highly accurate and robust instrument used to measure displacements across cracks and joints of a structure. The potentiometer is installed across a crack or joint of the structure to be monitored, using either groutable or expanding shell anchors. As the crack expands or contracts, the change in the distance between the anchors causes the connecting rod within the potentiometer body to move. The movement of the potentiometer changes the output which determines the movement of the crack with high resolution and accuracy.
