Electrical anchor load cells

Electrical resistance anchor load cells consist of a ring-shaped stainless steel body which incorporate from 8 to 16 electrical resistance strain gauges in a 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 diameter. A very stiff distribution plate is supplied, in order to ensure that the load is applied equally over the anular loading surface of the cell.
Readings are obtained with a CRD-400 hand held readout, Galvani readout or Leonardo datalogger.
