Joint Meter

The model IG2002 crackmeter

The model IG2002 crackmeter consists of a spring loaded, compression type vibrating wire displacement transducer and two installation brackets. One mounting bracket supports the displacement transducer while the other is anchored across the joint on to the reference surface. The spring-loaded shaft of the displacement transducer is always in contact with the reference surface at the other side of the crack. The sliding rod senses the movement between the two anchors and gives a frequency output which is read by the indicator.


Perimatrix joint meter/triaxial joint meter modal IG 2002xyz

For measurement in three orthogonal directions IG2002XYZ or perimetric joint meter is used. This version has three sets of displacement transducer assemblies installed across the crack in three mutually perpendicular directions. Free movement of the sliding shaft in all directions ensures accuracy of measurement.
