The triaxial jointmeter consists of two components. One component is a rigid arm that spans the crack. It holds a precision-ground reference block.
The other component holds the dial gauge so that it can obtain measurements of three sides of the reference block.
The tell-tale crack monitor is a simple, plastic device that is be installed across fissures to provide measurements in one or two directions.
Sisgeo Deformometer And Mechanical Jointmeters a large range of mechanical crackmeters (jointmeters) are produced to suit all the client requests.
- The removable deformeter allows to measure relative movements between two reference pins positioned across the joint (fissure).
- Supplied with carrying case it has a precise sliding rail with adjustable base length.
- Uniaxial and 3-D (triaxial) mechanical jointmeters are available to monitor joints and cracks.
- The movements between the two anchors are obtained with mechanical dial gauge.
- Simple and cheap, the TT-1 tell-tale crack-monitor installed across a fissure allows the crack survey in two directions.
