Load Cells (Electrical Resistance) | Model 3000

The Model 3000 Load Cell is made from an annulus of high-strength steel or aluminum, with electrical resistance strain gages in a Wheatstone Bridge configuration. The load cell is designed primarily for use on tiebacks and rockbolts, although they may be used during pile load tests and for monitoring loads in crosslot struts and tunnel supports, etc. In most cases, the load cells are used in conjunction with a hydraulic jack and bearing plates.

CALIBRATION OF HYDRUALIC JACKS AND LOADCELLS UP TO 1500 TONS CALIBRATION RESULTS ARE TRACEABLE BACK TO NIST.

Loadcell Calibrations

The hydraulic load cell uses a conventional piston and cylinder arrangement with the piston placed in a thin elastic diaphragm. The piston doesn’t actually come in contact with the load cell. Mechanical stops are placed to prevent over strain of the diaphragm when the loads exceed certain limit. The load cell is completely filled with oil. When the load is applied on the piston, the movement of the piston and the diaphragm results in an increase of oil pressure. This pressure is then transmitted to a hydraulic pressure gauge via a high pressure hose.
