Cảm biến đo biến dạng (VW Soil Extensometers) Geokon 4435
The Model 4435 Soil Extensometer is designed to be installed, in series, to measure horizontal strain 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. For measurement of strains in boreholes and RCC dams, please see the Model 4430 Deformation Meter.
