The Model 4435 Soil Extensometer is designed to be installed, in series, to measure horizontal strain and settlements in earthfill or rockfill dams. The 4435 has flanges on either end, which enable a series of extensometers to be bolted together forming long strings of sensors so that complete profiles of deformation or settlement can be monitored.
