Embedment Jointmeters
- Sisgeo Embedment Jointmeters to detect the movements between two anchors.
- It is suitable to be merged in concrete grouting, placing it across expansion joints, as usually occur in concrete dam.
- A thermistor allows temperature measurement for temperature compensation, if needed.
- It consists in two anchors, a vibrating wire displacement tranducer (DTE) and an external PVC casing.
- Instrument’s measuring range is pre-set to measure the traction/compression of 50% full scale.
- Any settings different from the standard can be requested to SISGEO in the purchase order.
