Electric Anchor Load Cells
- Sisgeo Electric Anchor Load Cells consists of a ring-shaped stainless steel body which incorporates from 8 to 16 electrical resistance strain gauges in full bridge configuration.
- Typical applications include performance testing of anchor systems in tunneling or deep excavations.
- The cell design minimizes the sensitivity to the eccentric load. Anchor load cells are available in a variety of ranges and diameters.
- A very stiff distribution plate is supplied, in order to ensure that the load is applied equally over the annular loading surface of the cell.
- Readings are obtained with C6003 pocket size digital indicator, GALVANI load cell readout, ADK-100 automatic data acquisition system or wireless technology.
