Push-in Type (VW) | Model 4830
Cảm biến đo ứng suất đáy móng Geokon 4830
The Model 4830 Push-In Pressure Cell is designed to be pushed in place for the measurement of total pressures in soils and earth fills. Where effective stress is required, the cell is fitted with an integral piezometer. A thread is provided on the end of the cell to allow for installation using lengths of pipe or drill rods.
