HYDRAULIC LOAD CELL www.enertec.ch

swiss sensor technology Description Hydraulic anchor load cells are used to monitor loads in tiebacks, rock bolts and cables. The hydraulic anchor load cell is a special ringshaped in stainless steel. Two plates welded along their perimeter and separated inside by a cavity saturated under vacuum with deaired oil to guarantee maximum rigidity. The applied load is transferred by means of oil to an analog pressure gauge that allows to immediately see the pressure in that moment. The ring-shaped load cell is chosen to suit the diameter and nominal load of the anchor. The same cell can be equipped...

swiss sensor technology Installation recommendations Anchor load cells have to be installed with partic- ular care to obtain load bearing surfaces flat and parallel to avoid any significant distortion under load. The specific design of these cells gives a very low sensitivity to the load eccentricity. Between the cell and wall surfaces it is usually installed an abutment plate. The plate shall be at least of the same thickness of the distribution plate (30 mm) with diameter at least 20 mm larger than the load cell. Please remember that after the anchor tension phase there is a release due to...
