- SME model 2070 series earth pressure cell are generally installed within fills to determine the total stress in Earthen Dam, embankment, fills, under railway track, pile foundation or piers.
- SME model 2071 series concrete pressure cells are used for measurement of total stresses in concrete Dam, retaining walls, culverts piles, slurry walls and beneath shallow foundations.
The basic construction of a vibrating wire earth pressure cell is basically comprises of minimum one active diaphragm mounted with a pretension vibrating wire pressure sensor. The gap between the pressure pad and sensor is filled with suitable oil (generally silicon oil). In quench tube model SME 2071 post stressing is possible after primary installation to avoid the shrinkage gap in concrete to fill up the air gap.
