C-1940 Crack Width Gauge Monitors

These crack gauges are composed of 2 pieces of acrylic and PVC sheet that overlap. One has an opaque marker and the other has an overlay marker on clear acrylic. Each half is attached to the structure on opposite sides of the crack. When the crack moves, the sides displace in relation to one another. Movement is then monitored by observing where the sight marks cross the displacement grid. Crack gages can be installed with screws or epoxy which we offer.

Crack gauges are available in several configurations. Quantity prices are available. The standard crack gauge is designed for flat applications either horizontal or vertical; the corner crack gauge is intended for purpose described. The displacement crack gauge monitors displacements in 3 directions. It monitors displacement and horizontal movement where there is a step across a crack due to displacement or out of plane movement. Crack gauge plus is like the standard gauge but it has the advantage of the user being able to measure using a caliper enhancing accuracy. Corner gauges and displacement gauges are sold in pairs. You may also download record cards to go with the crack gauges. Simply click on the name.
